At a potential hydroelectric site, the average gross head is 73m. It has 9m width and depth of 15m rectangular gate and average water velocity is 4.5 m/s. Assume a coefficient of discharge of 60.5%, leakage loss is 5% of the discharge load and the head utilized by the turbine blade is 60m. The loss in the turbine is equal to 3% of the gross head used. Determine: a. Penstock Efficiency b. Volumetric Efficiency c. Hydraulic Efficiency d. Mechanical Efficiency e. Electric Power Generated
