The pump of a water distribution system is powered by a 15-kW electric motor (efficiency = 90%). For the pump, (i) water flow rate is 50 L/s, (ii) the elevation difference across the pump is negligible, (iii) the inlet and outlet pipes have the same diameters, and (iv) the Pabs of pump are 100 kPa (inlet) and 300 kPa (outlet). Determine the (a) pump efficiency and the (b) T rise of water due to mechanical inefficiencies as it flows through the pump. Water 1 50 L/s 300 kPa , Imotor = 90% Motor 15 kW pump 100 kPa
