A pump transfers water uphill from one large reservoir to another, as shown in Fig. P5.21Ra. The difference in elevation between the two reservoirs is 100 ft. The friction head loss in the piping is given by where V is the average fluid velocity in the pipe and is the loss coefficient, which is considered constant. The relation between the total head rise, H, across the pump and the flowrate, Q, through the pump is given in Fig. 5.21Rb. If K_L = 40, and the pipe diameter is 4 in., what is the flowrate through the pump?
