Abstract

The need for energy that is getting bigger every day encourages people to choose energy sources from renewable energy such as water, wind, sun and others. The use of waterwheels now has been using as an energy conversion machine to produce electricity from water energy. The material of waterwheel blade greatly determines the performance of the waterwheel. This study aims to determine the effect of valve opening on fluid power to rotate the wheel with variations in blade material. The blade materials used are plastic, iron, and melamine. This study uses an experimental method by testing the waterwheel by varying the blade material with variations in valve opening. The results obtained that the largest fluid power for plastic material is 33.04017281 watt at valve opening 1 opening, iron material is 20.65680896 watt at valve opening 1, melamine material is 45.41550508 watts at valve opening 1.
