A hydraulic power system, as shown in the picture, has an elevation difference between the reservoir water surface and the downstream water pond surface of H( 7 m). A discharge of 0.8 m3/s flows through the penstock and spins a hydraulic turbine, which in turn drives a generator to produce electric power. Estimate the electric power generated if the head loss through the entrance, penstock and exit is 1 m, L and the efficiency of the turbine and generator are...
