4. The pump of a water distribution system is powered by a 15-kW electric motor whose efficiency is 90 percent. 300 kPa Pump Water 100 kPa 50 L/s pump "/motor-90% Motor 15 kW Answer: 70.37% The water flow rate through the pump is 50 L/s. The diame- ters of the inlet and outlet pipes are the same, and the eleva- tion difference across the pump is negligible. If the pressures at the inlet and outlet of the pump are measured to be 100 kPa and 290Kpa (absolute), respectively, determine the mechanical efficiency of the pump.
