A hydraulic jump is a rather sudden change in depth
of a liquid layer as it flows in an open channel as shown in
Fig. P4.25 and Video V 10.6. In a relatively short distance
(thickness = e) the liquid depth changes from ZI to Z2' with a
corresponding change in velocity from VI to V2• If VI =
1.20 ftls, V2 = 0.30 ft/s, and e = 0.02 ft, estimate the average
deceleration of the liquid as it flows across the hydraulic jump.
How many g's deceleration does this represent?
