A water turbine is placed at the bottom of a hill. It receives Q = 30 m3/s of water from a large lake at the top of the hill. The elevation difference between the turbine and the free surface of the lake is h = 100 m. Water leaves turbine with the speed V2 = 2 m/s. Head loss in the water supply pipe connecting turbine and the lake is 20 m. Calculate power (in MW) transferred from the water to the turbine.
