Question
In the region just downstream of a sluice gate, the
water may develop a reverse flow region as is indicated in Fig.
P4.59 and Video V10.9. The velocity profile is assumed to con-
sist of two uniform regions, one with velocity Va 10 fps and
the other with V, = 3 fps. Determine the net flowrate of water
across the portion of the control surface at section (2) if the
channel is 20 ft wide.
