Question:

A village with 55 households currently spends $4600 for electricity per month at a rate of $0.12/kWh. To meet electricity needs of the village, an engineer proposes to convert mechanical energy of a waterfall in the village into electricity by a hydraulic turbine. The waterfall extends to a height of 80 m from the ground level and the flow rate of the waterfall is 350 L/min. Assuming a turbine-generator efficiency of 82 percent, determine if the proposed turbine can meet the electricity needs of the village. Assume the operating and maintenance expenses are negligible and the turbine can operate nonstop throughout the year.
