In a hydroelectric power plant, water at 20°C is supplied to the turbinë at a rate of 0.8 m3/s through a 200-mlong, 0.35-m-diameter cast iron pipe. The elevation difference between the free surface of the reservoir and the turbine discharge is 70 m, and the combined turbine- generator efficiency is 84 percent. Disregarding the minor losses because of the large length-to-diameter ratio, determine the electric power output of this plant.
