Performance of dethridge wheel as low head power generator and loss analysis

Abstract

This research to measure the performance of dethridge wheel using a very low head as a driving force and analyze losses in the testing system. The parameters measured in this research are flow rate (m3/s), water velocity (m/s), water level (m), torque (Nm), and rotation (rpm). Debit is a variabel that is given treatment with variations in the difference between the initial flow rate and the next is 0.002 m3/s. The highest efficiency resulted in the first flow rate of 43.314% with hydro power of 1.862 watts and the power of the water wheel 0.806 watts. The higher increase flow rate causes the losses that occur are also grater, the state of the flow is more turbulent, and the loss due to force and fiction increase water.
