At point D it is divided into two branches. A 50-cm-diameter, 600-m-long pipe (f=0.024)
connects to reservoir B while a 60-cm-diameter, 1200-m-long pipe (f = 0.02)connects to
reservoir C. The surface elevations at A, B, C, and D are 30 m, 20 m, 10 m, and 25 m,
respectively. Determine the flow in each pipe.
