Water flowing at a velocity of 5 ft/sec in rectangular open channel of width 5 ft and depth 4 ft (control face 1) diverges into two smaller rectangular open channels. The channel at control face 2 is of 3 ft width and depth 3.5 ft, and the channel at control face 3 is of 2 ft width and depth 1.5 ft and flows at a velocity of 8 ft/sec, as illustrated in Figure ECP 3.68. (a) Determine the volume flowrate at each of the three control faces and the velocity at control face 2
