A hydraulic jump is formed in a 7.5-ft-wide rectangular channel which carries a specific discharge of 25.0
 /s. Determine the jump height and efficiency if the downstream depth is 6.5 ft.

A trapezoidal channel of 2.0 m bed width and 3: 2 side slope carries a discharge of 10.0
 /s with a depth of flow of 0.5 m. Determine whether the flow is supercritical or subcritical. If a hydraulic jump were to form, what would be its height and efficiency?
