Q6) An oil pump is drawing (25 kW) of electric power while pumping oil with (= 860 kg/m3) at a rate of (0.1 m3 /s). The inlet and outlet diameters of the pipe are ( 8 cm and 12 cm), respectively. If the pressure rise of oil in the pump is measured to be (250 kPa) and the motor efficiency is (90 percent), determine the mechanical efficiency of the pump. Pump 8 cm 12 +4 SOUDA AP=250 kPa 25 kW Motor
