In this experiment we were able to control the rate and flow of the water. We were also able to control where the water hit the propeller. The slope of the penstock was also a variable in our experiment. The slant of the penstock would have changed the waters rate of flow, so we would have been able to create more power. A longer penstock would have made a difference because then the water would hit the propeller with more force, causing the propeller to spin faster. The experiment would have changed if we had a bigger Tupperware container so that we could hold more water. We could have created more power because the force of the water hitting the propeller would have been greater producing more energy. Provided we had a larger propeller we would have more surface area for the water to hit. If the propeller was touching the water it would effect how fast the propeller could spin creating resistance. Our project on a larger scale would be able to create a larger amount of energy.
