A pump draws water from a reservoir with water elevation at 1000 feet and discharges to a large-diameter tank with the water level at 1050 feet. The discharge line of the pump is 1000 feet of 4" PVC. The suction line is short, so head loss in the suction line may be neglected. The pump curve is given below. What is the operating point of the pump (give both GPM and feet of head)? Explanation: List three other factors to consider – in addition to the discharge and head- in selecting a pump for the situation described in problem 4.
