Electric 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 3000 kg/s steadily. If the mechanical power output of the turbine is 800 kW and the electric power generation is 750 kW, Determine the following: a. turbine efficiency b. combined turbine-generator efficiency of this plant. Friction in pipes = 10% of available potential energy.

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.
