## Abstract

The purpose of this experiment was to determine the correlation of the height and the diameter of a pipe on the possible peak voltage of a waterwheel hydroelectric generator. The research is attempting to better understand the relationship between the height and the diameter of a pipe on the possible peak voltage. The hypothesis tested was If the diameter of the pipes are enlarged and the total height is raised, then more energy will be produced. The data supports this hypothesis and suggests that there is a significant difference between the effect of height and the diameter of a pipe on the peak energy produced. The voltage was recorded with a voltmeter. The waterwheel was below a pipe that was connected to a bucket with a hole, which then had water poured through which spun a waterwheel connected to a DC motor, producing energy. The research indicated that there is, indeed, a significant difference between the results of each set of variables. The research defines the correlation of the height and the diameter of a pipe (Independent Variables) on the mean peak voltage (Dependent Variable) produced with a waterwheel.
