Hydraulic Jump

A rectangular open-channel flume is used to create a hydraulic jump. The upstream and downstream water depths of the jump are measured at 0.5 ft and 3.5 ft, respectively. The channel width, b, is 10 ft.

Students are asked to determine the Froude number and velocities before and after the jump. Also plot the specific energy and specific force diagrams. Indicate the hydraulic jump process on each diagram.

• Assume the flow far away from the jump is steady, uniform and one-dimensional.
