2. A centrifugal pump delivers 700 L/s of water against an elevation head of 40m when rotating at the angular velocity of 2450 rpm. If the torque measured at the driving shaft of the pump is 1650 N.m, determine the efficiency of the pump. If the pump is being operated by a 600 kW motor, what is the efficiency of the motor? What is the overall system efficiency?
