An oil pump is drawing 44 kw of electric power while pumping oil with rho = 860 kg/m^3 at a rate of 0.07 m^3/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 500 kpa and the motor efficiency is 90 percent, determine the mechanical efficiency of the pump. (round the final answer to one decimal place.)
