In Figure PS.7.2, each pipe has the following properties: D = 3 ft, L = 5,000 ft, and .f = 0.02.
The two pumps are identical; the pump characteristics are shown in the following table. The water surface elevations are 80.0 ft in reservoir A and 94. 0 ft in reservoir D. The discharge in pipe BC is 20 cfs in the direction from B to C. Determine (a) the discharge in AB and BD, (b) the water surface elevation in reservoir C, and (c) the head added to the flow by each pump.
