3. The pump of a water distribution system is powered by a 15 kW electric motor whose efficiency is 90%. The water flow rate through the pump is 50 L/s. The diameters of the inlet and outlet pipes are the same and the elevation difference across the pump is negligible. If the pressures at the inlet and outlet of the pump are measured to be 100 kPa and 300 kPa respectively. Determine the following: a.) efficiency of the pump b.) determine the temperature rise of water as it flows through the pump due to the mechanical inefficiency.
