3- The pump of waste water of concentration (1.5 mg/liter) treatment plant system is powered by a (15 kw) electric motor whose efficiency is (90%). The water flow rate of the pump is (50 L/sec).The diameter of the inlet and outlet pipes are the same, and the elevation difference across the pump is negligible. If the pressure at the inlet and outlet of the pump are measured to be (100 Kpa) and (300 kpa) absolute, respectively. Determine the mechanical efficiency of the pump.
