Chapter 4, Problem 4.59(choose chapter or problem)
In the region just downstream of a sluice gate, thewater may develop a reverse flow region as is indicated in Fig.P4.59 and Video V10.9. The velocity profile is assumed to consistof two uniform regions, one with velocity Va = 10 fps andthe other with Vb = 3 fps. Determine the net flowrate of wateracross the portion of the control surface at section (2) if thechannel is 20 ft wide.
