A water system with a capacity of 100 gpm has a total head of 240 ft at the suction line of a single-stage two pole, centrifugal pump. The maximum efficiency for the pump is most nearly?
I understand that one can use the flow rate, motor data, and head added (ha), to calculate the specific speed which leads to the answer. What I dont understand is why 240ft. is considered the head added. The problem indicates that this is the pressure on the suction side of the pump. What gives?
