A 440 volt, 60 Hz, 4-pole. 3-phase induction motor is directly coupled to a water pump that delivers 1000 cfm of water against a head of 9.5 ft. At this condition, the induction motor draws a line current of 23.32 amperes at 90% power factor. If the motor loss is 1.5 kw, Determine the efficiency of the pump.
