The purpose of this experiment was to design and complete an experiment that will help our team understand the energy efficiency of the energy transfer generator with a wind turbine assembly. Our question asked was how does the energy efficiency of the system change when the incident wind speed is changed? Our group predicted that at lower wind speeds we will get less energy output from our wind turbine generator. One 20”, 3 speed box fan was used to supply our energy input for the experiment. We calculated the energy input by the formula ½ x p x A x v³. Where (p) was the air density 1.2 (source wikipedia), (A) was the turbine area, and (v) was the wind speed. This equation gave us the available power in watts. Next was one ring stand that was used to hold up our pasco energy transfer generator with a wind turbine attachment. This set up was used to calculate our energy output for the experiment. In our experiment we also had one meter stick which was used to set a distance from the fan to the generator, find the distance from the turbine to the table, and find the
