Power for Pumping in a Flow System. Water is being pumped from an open water reservoir at the rate of 2.0 kg/s at 10°C to an open storage tank 1500 m away. The pipe used is Schedule 40 3-in. pipe and the frictional losses in the system are 625 J/kg. The surface of the water reservoir is 20 m above the level of the storage tank. The pump has an efficiency of 75%. What is the kW power required for the pump? If the pump is not present in the system, will there be a flow? Ans. (a) 1.143 kW
