Water flows through a turbine at rate of 1.6 m3/s from point A to point B which is 2m below the former. The pressures at A and B are 251.4 kPa and -104.4 kPa, respectively. The diameter of pipe at A is 400mm while diameter of pipe at B is 950mm. The head loss is 2m. How many kW are delivered by the water to the turbine?
