In a hydroelectric power plant, water at 20℃ is supplied to the turbine at 1.2 m3/s through a 200 m long, 0.35 m diameter cast iron pipe. The elevation difference between the free surface of the reservoir and the turbine discharge is 115 m and the combined turbine/generator efficiency is 80%. Disregarding minor losses, determine the electric power output (kW).
