Question: electric power is to be generated by installing a dydreaulic turbine generator at a site 7 0 m below the free surface of a large

electric power is to be generated by installing a dydreaulic turbine generator at a site 70 m below the free surface of a large water reservoir that can supply water at a rate of 1500 kg/s steadily. If the mechanical power output of the turbine is 750 kW and the electric power generation is 600 kW, determine the turbine efficiency and the combined turbine generator efficieny of this plant.
