Term 2 Week 10 Reflection--Jun Jie

During our post exam activity, we were briefed on what was going to happen after the school holidays. We were told to post a photo of our product, our report, photo of our group, our presentation, and our video on the blog for the final post. I have assigned Jun Rong to assign us on what to do for the report while I work on our product.

Term 2 week8 reflection- Jun Rong

This week is our examination period, we cannot discuss much about our products. We will be gathering facts on who to do what for the 2000-3000 words about the explanation of our products next week.

Term 2 Week 9 Reflection--Jun Jie

In this week, we were told to make a presentation for our ipw project. I have assigned Isaac to create the skeleton of the presentation, send it to me for editing before we finally post it on the blog

Term 2 Week 8 Reflection--Jun Jie

Like the previous week, this week is also our examination period, therefore we were not able to meet up. I will be discussing with the other group members on how to find a suitable fish tank, as this is our only missing item.

Term 2 Week 7 Reflection--Jun Jie

As this week is the examination week, we are not able to make any progress at all. I also have not been able to find a suitable fish tank, but i did found the blades of an old fan

Term 2 Week 6 Reflection--Jun Jie

In this week, I have allocated the various task for each member to do, such as the gathering of all our research and the making of our presentation. I will be making the model once I managed to find the suitable fish tank and fan.

Term 2 week 4 reflection- jun rong

My group leader had told us to gather all the materials for the boat, I am suppose to fiind for u-shape,bar-magnet and light bulb. I spent quite along time at some shops but cant find it I will continue to find those products. After gathering those products we will then try to build the boat.

Term 2 Week 5 Reflection--Jun Jie

In this week, we have not completely collected all the materials. We have thus discussed the various places which we can buy the materials, such as Sim Lim Tower and other electronics shopping malls. The 2 items that would be of difficulty to find is the Tank and the Blades of the fam

Term 2 Week 4 Reflection--Jun Jie

In this week, I listed down the things that we needed to collect to build the model to show the concept of hydroelectricity. The materials are as such:

1) 4 bar magnets/a big cube magnet

2) 1 large U-Shaped magnet

3) 1 electrical light bulb or a LED Light

4) Wires

5) Blades of the fan

6) Big Plastic fish tank

7) 30cm Metal Rod

We will gather the materials by 30th April, and I will create the product on Labour Day. Isaac is left in charge to create the powerpoint of our presentation

Term 2 Week 3 Reflection--Jun Jie

In this week, we managed to collate the data of the survey. As there is an equal percentage (50-50) in the question "Do you think boats are useful?", we decided to just make a model that shows the concept of hydroelectricity.

The model will be based on what happens in a dam, like the different parts and processes. We are currently looking around the web, looking at how others make their miniature models of the dam and models that shows the concept of hydroelectricity

Term 2 Week 3 reflection-Jun Rong

Some ideas for the hydro-electric boat. In order to make the boat as fast as possible We got to use a modified 48 volt brushed motor from a forklift used to power the hydraulics, rated at about 15hp such as lithium polymer batteries. we also got to use the set of turbines blades and motors. Waterproof materials are needed

Water turbines generate very reliable power with a very simple design. Some kind of "runner" or is attached to a propeller shaft that operates an alternator to generate power when water turns the runner. There are quite a few types of turbines, but they fall into three major styles: impulse turbines, reaction turbines and submersible propeller turbines. Each is ideally suited for a different type of water supply. No matter what source of running water you have on your property, if it supplies a year-round flow of water, there is most likely a water turbine well-suited to provide electricity for you.

Customising water output is also important during the use of the hydro-electric boat. Some ideas are

Water turbines come in a range of output voltages, to match the overall voltage of your electrical system. While 12 volt is common for small to mid-sized systems, large systems can be designed in 24 or 48 volt configurations. For marine use, most boats will have a 12 volt system.

For impulse-style turbine systems, power output can be increased in high-flow sites by using multiple nozzles on the runner enclosure and/or using a larger diameter runner. Many reaction style turbine models also come with the option for two or more runner diameters, with the larger option providing more power for higher flow sites.

In sites with sufficient water flow volume, multiple turbines of any style, or a mix of different styles in some cases, can be assembled into a single high-output system.

thats all I've researched

Term 2 week2 reflection-Jun Rong

In this week we are still processing on how to send the surveys to our friends . Now we have 55 people done our survey. Currently our group leader Ong Jun Jie is combining all the reflection to form a chart and graph on what people think about hydro-electric boat

Term 2 Week 2 Reflection--Jun Jie

In this week, we managed to get enough data for our survey. I am currently compiling all the datas and organizing them into charts. The data will be soon posted on the blog.

Week 6 Reflection- Isaac Phua

This week our group created a survey to find out what the public thinks about hydroelectricity and boats
What i know about the surveys:
I know that surveys are made to find out views from the public, what they know and think about a certain subject. Surveys are used to make improvements after looking at what the public thinks about a certain subject.
What i think about the surveys:
I think that surveys are a useful way of collecting information from the public and to find out what the public thinks about a topic
What i found out in the survey:
We have not published the survey so we have not gather any information yet.
What i can do after the survey:
After doing the survey we can use the information gathered and put it into a graph or chart to compare the information

Week 6 reflection- Jun Rong

This week, my group created a survey to find out the view of the public about hydro electric boats.

What I know about surveys:

I know that surveys are used to collect information about the subject it is surveying about. It is used to find out the view of the audience/public for either suggestions or improvements. It may also ask about the opinion of the audience/public about the subject. Surveys are flexible in the sense that a wide range of information can be collected.

What I think about surveys:

I think that surveys are extremely useful in terms of getting and collating information as it is very easy to administrate and collate the data. I feel that surveys that just involve "yes and no" questions may be less effective in collecting these data.

What I found out in the survey:

Because our group has not completed publishing the survey, we do not have much information. But, we now know about what we need to find out from the public.

What I can do after the survey:

Even though we have not created the survey, we expect to collate the data and present it in a form of a pie chart for questions that asks about the audience's opinion. Also, with the data, we will have a better understanding about what we would have to do and would be able to proceed with creating our product.

Week 4 Reflection--Jun Jie

Due to our secondary 2 adventure camp this week, we missed our IPW period. However, we still managed to meet up just yesterday to discuss on the 4 main points of research/guiding questions. They are as follow:

1) What are the materials needed to built the boat?

2) How do we prevent the boat from sinking?

3) What is the maximum pressure on the ship before it feels strained?

4) The amount of force/electricity needed to be generated.

However, we also have other important sub-research questions, such as:

1) How to connect the turbine without using wires?

2) How are we going to find out the amount of electricity needed?

3) How are we going to counter the irregular frequency of the flow of water?

4) What are the properties of different turbines?

5) What are the standard rules for building the ship?

6) What are the factors that put pressure on the hull?

Therefore, the main 4 research questions are already split equally among the 4 of us (1 person research on 1 question). As for the sub-research questions, we believe that while searching on the main 4 questions, we will also be able to find the answer to these questions.

Worksheet 4

week 3 reflection- yonghwa

Some questions that are going around in my head :What is the maximum pressure on the ship before it feels strained?
What are the machines used to generate the structure of the ship?

3 Things I learnt: The hulls of ships are subjected to many factors of pressure from the number of loads.
: There are ship classification societies who have established standard form for full loads.
: modern CAD computer programs are usually used today to generate much more detailed and powerful computer models of the structure.

Ideas I agree with: The many factors of pressure from the number of loads are essential to find out to stabilize the ship

Worksheet 3

Week 3 reflection --Jun Rong

In this week, we had discuss about how to convert the kinetic energy into hydro-electric energy.
We had mainly focus on the process of conversion so that it will lessen the burden of the whole project.

Some questions that are still going around in my head:

What materials are we gonna use to replace those that are used on an actual life size boat?

How are we going to substitute the turbine with a turbine that is smaller?

3 things I learnt:

I learnt that you need a water-turbine storing underneath the boat so that energy will be converted easily

We need to measure how much force needed for the boat to move which depends on the structure and materials use for the boat.

The power in available in a stream of water is;

where:

• P = power (J/s or watts)
• η = turbine efficiency
• ρ = density of water (kg/m³)
• g = acceleration of gravity (9.81 m/s²)
• h = head (m). For still water, this is the difference in height between the inlet and outlet surfaces. Moving water has an additional component added to account for the kinetic energy of the flow. The total head equals the pressure head plus velocity head.

• = flow rate (m³/s)

Week 3 Reflection-Isaac

Some questions that are still going around in my head
1] How are we going to make or gather the materials needed to substitute the materials used to make a actual life size boat?
2] Which turbine to use for our hydroelectric boat?

3 things i learned
1] I learned that there are water is channeled at high speeds through turbines which generate electrical energy when the water turns them.
2] I learned that reaction turbines are acted on by water, which changes pressure as it moves through the turbine and gives up its energy.
3] I learned that a water turbine is a rotary engine that takes the movement of water and convert it into other forms of energy mainly electricity.
Ideas that i agree with
I agree that hydroelectric energy is a renewable energy that could be used to replace fuels. I also agree that we should decide how fast the boat can go before deciding what turbines are suitable to use in the boat.

Week 3 Reflection--Jun Jie

In this week, we have discussed on the main focus of the project, which is to give the members a better understanding of hydroelectricity and its concept, like how to calculate it and the factors affecting it.

Some questions that are still going around in my head:

What materials are we gonna use to replace those that are used on an actual life size boat?

How are we going to substitute the turbine with a turbine that is smaller?

3 things that I learnt:

1) The formulae to calculate hydroelectricity is P = ρhrgk

2) The turbine that we have to installed is known as Hydraulic Turbine

3) Water turbines are divided into two groups; reaction turbines and impulse turbines.

Ideas I agree with:

In order to power the boat, we have to find the amount of energy required to run the boat first before we can find out the speed at which the boat should move in order to gather enough water which would turn the turbine.

New Research Details

Question: What materials are needed to make the turbine and engine of both the boat and the generator? What type of turbines and engines ? What are the concept behind the creation of the turbine and electric generator?

Hydraulic Turbine also know as water turbine. A water turbine is a rotary engine that takes the movement of water and convert it into other forms of energy mainly electricity. It is a clean and renewable source of energy.
Water wheels have been used for thousands of years for industrial power. Their main shortcoming is size, which limits the flow rate and head that can be harnessed. The transformation from water wheels to modern turbines took about a hundred years. Development occurred during the Industrial revolution, using scientific principles and methods. They also made extensive use of new materials and manufacturing methods developed at the time.
Flowing water is directed on to the blades of a turbine runner, creating a force on the blades. Since the runner is spinning, the force acts through a distance (force acting through a distance is the definition of work). In this way, energy is transferred from the water flow to the turbine.
Water turbines are divided into two groups; reaction turbines and impulse turbines.
The precise shape of water turbine blades is a function of the supply pressure of water, and the type of impeller selected.
Reaction turbines
Reaction turbines are acted on by water, which changes pressure as it moves through the turbine and gives up its energy.
They must be encased to contain the water pressure (or suction), or they must be fully submerged in the water flow. Newton's third law describes the transfer of energy for reaction turbines.
Most water turbines in use are reaction turbines and are used in low (<30m/98ft) and medium (30-300m/98-984ft)head applications. In reaction turbine pressure drop occurs in both fixed and moving blades.
Impulse turbines
Impulse turbines change the velocity of a water jet. The jet impinges on the turbine's curved blades which change the direction of the flow. The resulting change in momentum causes a force on the turbine blades. Since the turbine is spinning, the force acts through a distance (work) and the diverted water flow is left with diminished energy.
Prior to hitting the turbine blades, the water's pressure (potential energy) is converted to kinetic energy by a nozzle and focused on the turbine. No pressure change occurs at the turbine blades, and the turbine doesn't require a housing for operation.
Newton's second law describes the transfer of energy for impulse turbines.
Impulse turbines are most often used in very high (>300m/984ft) head applications .
Pumped storage
Some water turbines are designed for pumped storage hydroelectricity. They can reverse flow and operate as a pump to fill a high reservoir during off-peak electrical hours, and then revert to a turbine for power generation during peak electrical demand. This type of turbine is usually a Deriaz or Francis in design. Types of water turbines


Various types of water turbine runners. From left to right: Pelton Wheel, two types of Francis Turbine and Kaplan Turbine
Reaction turbines:
Francis
Kaplan, Propeller, Bulb, Tube, Straflo
Tyson, Gorlov (Free-flow types)
Water wheel
Archimedean screw turbine
Impulse turbines:
Pelton
Turgo
Michell-Banki (also known as the Crossflow or Ossberger turbine)

Design and application

Turbine selection is based mostly on the available water head, and less so on the available flow rate. In general, impulse turbines are used for high head sites, and reaction turbines are used for low head sites. Kaplan turbines with adjustable blade pitch are well-adapted to wide ranges of flow or head conditions, since their peak efficiency can be achieved over a wide range of flow conditions.
Small turbines (mostly under 10 MW) may have horizontal shafts, and even fairly large bulb-type turbines up to 100 MW or so may be horizontal. Very large Francis and Kaplan machines usually have vertical shafts because this makes best use of the available head, and makes installation of a generator more economical. Pelton wheels may be either vertical or horizontal shaft machines because the size of the machine is so much less than the available head. Some impulse turbines use multiple water jets per runner to increase specific speed and balance shaft thrust.Runaway speed
The runaway speed of a water turbine is its speed at full flow, and no shaft load. The turbine will be designed to survive the mechanical forces of this speed. The manufacturer will supply the runaway speed rating
Maintenance
Turbines are designed to run for decades with very little maintenance of the main elements; overhaul intervals are on the order of several years. Maintenance of the runners and parts exposed to water include removal, inspection, and repair of worn parts.
Normal wear and tear includes pitting from cavitation, fatigue cracking, and abrasion from suspended solids in the water. Steel elements are repaired by welding, usually with stainless steel rod. Damaged areas are cut or ground out, then welded back up to their original or an improved profile. Old turbine runners may have a significant amount of stainless steel added this way by the end of their lifetime. Elaborate welding procedures may be used to achieve the highest quality repairs.
Other elements requiring inspection and repair during overhauls include bearings, packing box and shaft sleeves, servomotors, cooling systems for the bearings and generator coils, seal rings, wicket gate linkage elements and all surfaces.

Week 2 Reflection- Isaac Phua

In this week, our group have decided on the topic to work on, it is the Theme of Champions of the Earth. All of us have been assign a job, which is to research on a question we thought of and discuss
it on the next IPW lesson. My question is what materials are needed to make the turbine and engine of both the boat and the generator.

What i already know about the topic?
I know that the earth is currently suffering from global warming which is carbon emissions released by burning fuel and other objects will create a hole in the atmosphere allowing sunlight to pass through directly causing the earth to heat up. Thus, causing the ice in the north and south poles to melt. Due to this phenomenon many animals will become extinct as they will lose their habitats.

What questions i want to ask about this topic?
What materials are needed to make the turbine and engine of both the boat and the generator? What type of turbines and engines ?

What are the subject/skills i can make of ?
I can use the skills of research and analysing to understand the topic i am researching. I can also use the skill of brainstorming and creativity.

Where can i go to find information for our project ?
I can find the information for our project in the internet or the library

What do i want to tell others about our project?
I am going to tell other about the type of turbine and engines and the materials needed to make them.

A few useful videos

I will like to share a few useful videos about the concepts of converting kinetic energy to electrical energy.

Here are the links for the videos

http://www.youtube.com/watch?v=tt_lqFyc6Co&feature=related

http://www.youtube.com/watch?v=htT_8sFJx1w

So basically the concepts behind these videos are kinetic energy can be converted to electrical energy using hydraulic dams, sea barrages etc. The water ( in this case ) is channeled at high speeds through massive turbines which generate electrical energy when the water turns them.

I can use the skill of research to know more about the topic. I can also use innovation to think of replacement objects to replace the actual objects used to make an actual life-size boat.

Where can I go to find information for our project:

I can learn more about the subject at the NLB, or the MRL, or even the internet from websites such as wikipedia.org

What do I want to prepare to tell others about out project:

I am required to prepare to tell my team members about the concept of hydroelectricity and how it is being calculated, as well as the amount of electricity we need to power the boat.

Week 2 Researches

Worksheet 2

Week 1 Reflection-Yong Hwa

This week, we managed to get the name of our group: "The Eco-Champs". We named this group as our theme is about going green. Global warming is becoming more inportant in the present world. Many people know about the effects of global warming. Yet, they are not taking any actions. Me and my fellow teammates are going to do our part for the world. We will be making innovative products that will help save the environment.

The first item I am thinking of is: a type of eco-friendly type of material that can be used to make into a kind of bag, that can be brought to market for shopping. It will reduce the plastic bags used and it can be used over and over again.

Week 1 Reflection-Isaac

In this week we did managed to decide our group name, thought of some ideas and decided the group roles. We decided to think of ways to prevent or slow down global warming. I had decided 2 ideas for the project.
1] It is to create an object like the fan which is normally powered by electricity but instead i would like to try using solar energy collected using solar panels to power the fan. That would allow us to save a lot of electricity as solar energy is renewable while electric energy produce by fuel is expensive and non renewable causes harm to the environment by emitting carbon emissions.
2] An torch light that can be powered by shaking it. The kinetic energy through shaking the torch light can be used by turning it into electricity.

Week 1 Reflection--Jun Jie

In this week, we have not done much. All we have completed is deciding our group name, which we concluded should be "The Eco-Champs", and assign roles to each members. We have also decided that our theme shall be "Champions of the Earth". 

Currently, I know that the earth is suffering from Global Warming, which causes the melting of ice caps, causing floods and arctic animals, such as polar bears, to lose their habitats and become endangered. 

Therefore, I would like to find out ways to make our future a "Greener" one by finding out ways to reduce the amount of Carbon Dioxide emissions from vehicles. I will therefore research further on both Global Warming and How to prevent it from happening, besides conserving energy by using green energy like solar or hydroelectric energy.

Here are the ideas of our project (our group has decided that each one of us shall think of at least 2 ideas for the project, and we will then vote for the best one to be carried out)

1) An object to either absorb or dissolve the carbon dioxide emissions. (Something like an air freshener, but an air freshener only refreshes the air and does not remove these emissions.)

2) A "membrane" type of material that would prevent the carbon dioxide emissions from coming out of the car. (Like a filter paper, but instead this blocks the gas from escaping)

3) A hydro-electrical Power Boat

Week1 refelction--- Jun Rong

In this week, we manage to do most of the basic stuff like naming the group and the roles of each and every members. What we going to do for this grace project is basically about global warming and become the "champion of the earth"

Currently the earth is suffering for great pollution by man-kind which causes global warming, therefore I will like to prevent all this events to happen by doing out. I will be research on conserving energy and reduce the use of fossil fuels, as well as researching on how to reduce the emission of carbon dioxide in our environment without using slow methods like growing more trees which will take quite some time for it to be fully-grown

Here are the ideas of our project (our group has decided that each one of us shall think of at least 2 ideas for the project, and we will then vote for the best one to be carried out)

1) Create a solar panel window which abosrbes light energy and converts it to different form of energy, it is different from the solar panel because it only needs a minimum of light, as long as it is not in the night, it can be able to function

2) A fan-like machine that absorbs carbon dioxide and when input into the computer, it cools the computer from overheating using the carbon dioxide absorbed. (something like a fan-control which uses the energy converted from carbon dioxide to cool down your computer)

GRACE Lesson 1

In this week, we basically had a rough introduction of what we are going to for our IPW. As I was away to help out in the Secondary 1 camp, I had to rely on my teammates to convey some instructions and other informations
