A pump supplies water at a flowrate of 4 ft3 /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%. 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 d. Amount that the company will pay in using the pump for a day if the power rate is Php8.17/KW-h
