Water enters a 5-ft-wide, 1-ft-deep channel as shown in Fig.P4.66. Across the inlet the water velocity is 6 ft/s in the centerportion of the channel and 1 ft/s in the remainder of it. Fartherdownstream the water flows at a uniform 2 ft/s velocity across theentire channel. The fixed control volume ABCD coincides withthe system at time t = 0. Make a sketch to indicate (a) the systemat time t = 0.5 s and (b) the fluid that has entered and exited thecontrol volume in that time period.
