An oil pump is drawing 18 KW of electric power while pumping oil with density 860 kg/m at a rate of 01 m /s. The inlet and outlet diameters of the pipe are 8 cm and 17 cm, respectively. If the pressure rise of oil in the pump is measured to be 250 kPa and the motor efficiency is 95 percent, determine the mechanical efficiency of the pump. Take the kinetic energy correction factor as 1,05. IBEW Decm Pump Oil AP - 250 APA 0.1 m'/ The mechanical efficiency of the pump is 51.6 0%
