Water from a large tank is used to generate electricity by installing a hydraulic turbine- generator at 100 m down from the water surface as shown in Figure QS. The water is supplied to the turbine at a rate of 2000 kg's. If the mechanical power input of the turbine is 1800 kW and the generator efficiency is 80%, determine the percentage reduction of efficiency between generator alone and combination of turbine-generator Consider the water density as 1000 kg/m (7...
