A pump transfers water from the upper reservoir to the lower one as shown in the figure (a) below. The difference in elevation between the two reservoirs is 100 ft. The friction head loss in the piping is given by KV2/2g, where V is the average fluid velocity in the pipe and K is the loss coefficient, which is considered constant. The relation between the head added to the water by the pump and the flowrate, Q, through the pump is given in Figure (b) below. If KL = 17, and the pipe diameter is 4 in., what is the flowrate through the pump? Q= i ft/s 100 ft Pump 300 5200 Pump head, ft of water 100 0 1 (b) (a) Q. ft/s 2 3
