My experiment
HYDRO ELECTRICITY - PIPE SIZE AND ENERGY OUTPUT
RESEARCH QUESTION:
How does the size of the pipe affect the the number of times the water wheel turns.
HYPOTHESIS:
That a larger pipe will make the water wheel turn more per milliliter than a smaller pipe.
INTRODUCTION:
Hydroelectric power stations create electric. They do this by using water to turn a turbine. A considerable amount of science and engineering reseash is used to make this experiment, we were interested in seeing how the pipe size would make the most energy.
WHAT WE USED:
2 x yogurt containers
2 x pipes (1 x 6 mm,1 x 3mm)
1 x water wheel (marked to determine the number of turns)
1 x jug with 500 mL of water
METHOD:
Place different sizes in the yogurt containers. Put the yogurt containers filled with 500mL of water on top of the water wheel. Time how long it takes for the container to empty.
RESULTS:
The 6mm pipe lasted 16.3 seconds on average and the 3mm pipe lasted 32.3 seconds on average. For 500mL the 6mm pipe turned 33 revolutions (on average) and the 3mm pipe turned 57.6 revolutions on average.
CONCLUSION:
The experiment found that the smaller pipe (3mm) caused the water wheel to turn more per 500mL than the larger pipe (6mm). The water took longer to come out of the smaller pipe so greater times were recorded when using this pipe, which means the small pipe makes more energy than the big pipe.
