Question 18 (10 April 2020) 51.5 kW 12 cm Pump An oil pump is drawing 51.5 kW of electric power while pumping oil with p= 860 kg/m3 at a rate of 0.23 m3/s. The inlet and outlet diameters of the piper are 8 cm and 12 cm, respectively. If the pressure rise of oil in the pump is measured to be 500 kPa and the motor efficiency is 87.5 percent, determine the mechanical efficiency of the pump. Motor 8 cm...
