A pump supplies water at a flow rate of 4ft3/s from an open reservoir through a horizontal 8-in sched 40 pipe. The head loss from the reservoir to the suction of the pump is 2 ft-lbf/lbm, and the discharge is at 90 psig into a 6-in sched 80 pipe. The pump has an efficiency of 65% answer the following: a.) The head that must be delivered by the pump to the water is ________ or energy developed by the pump or output energy of the pump b.) input energy to the pump c.) Rated power of the pump in kW
