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

Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.
