actual power by generator = 750 kw
power produced by generator = 750/.75 =1000 kw
mechanical power= generator power/ effciency of turbine
= 1000/08 =1250 kw

9) Electrical power is to be generated by installing a hydraulic 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 800 kW and the electric power generation is 350 kW, determine the turbine efficiency and the combined turbine-generator efficiency of this plant. Neglect losses in the pipes. (10pts).
