Electric power is to be generated by installing a hydraulic turbine-generator at a site H m below the free surface of a large water reservoir that can supply water steadily at a rate of 900 kg/s. If the mechanical power output of the turbine is 800 kW and the electric power generation is 750 kW, determine the turbine efficiency and the combined turbine- generator efficiency of this plant. Neglect losses in the pipes.
