A pump transfers water from the upper reservoir to the lower one as shown in Fig. P5.83a. The difference in elevation between the two reservoirs is 100 ft. The friction head loss in the piping is given by is the average fluid velocity in the pipe and KL 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 Fig. P5.83b. If K_L= 20, and the pipe diameter is 4 in., what is the flowrate through the pump.
