Electric power is to be generated by installing a hydraulic turbine—generator at a site 120 m below the free surface of a large water reservoir that can supply water steadily at a rate of 930 kg/s. If the mechanical power output of the turbine is 850 kW and the electric power generation is 770 kW, determine the turbine efficiency and the combined turbine— generator efficiency of this plant. Neglect losses in the pipes

Electric power is to be generated by installing a hydraulic turbine—generator at a site 120 m below the free surface of a large water reservoir that can supply water steadily at a rate of 930 kg/s. If the mechanical power output of the turbine is 850 kW and the electric power generation is 770 kW, determine the turbine efficiency and the combined turbine— generator efficiency of this plant. Neglect losses in the pipes.
Electric power is to be generated by installing a hydraulic turbine-generator at a site 120 m
below the free surface of a large water reservoir that can supply water steadily at a rate of 930
kg/s. If the mechanical power output of the turbine is 850 kW and the electric power generation
is 770 kW, determine the turbine efficiency and the combined turbine- generator efficiency of
this plant. Neglect losses in the pipes.
