Water flows through the 4-ft wide rectangular channel at a rate 30 ft3/s. The depth of water upstream the potential hydraulic jump is 1 ft. Show a labelled illustration of the channel based on the information provided. Determine whether the hydraulic jump will form or occur. If the jump occurs, evaluate its depth, y2 and its corresponding Froude number. Evaluate the energy head loss in the jump and relative to initial energy head, do you think this head loss is...

2. A 2.5 m wide rectangular channel conveys m wide rectangular channel conveys water at a normal depth of 2 m. In a part of the channel, the channel width is expanded to 5 m. The local energy loss due to this expansion is about 10% of the upstream velocity head. If the channel slope is 0.03% and the Manning roughness coefficient is about 0.012, calculate the water depth over this transition and show the situation with a simple sketch.

A trapezoidal channel has a side slope of 1:1 and a bed width of 6.0 m. A hydraulic jump with a height of 0.5 m (i.e. the difference between water surface elevation upstream and downstream of the jump) is encountered in the channel. If the channel has a discharge of 10 m3/s, determine the critical depth in the channel. Plot the momentum curve and determine the flow depth immediately upstream and downstream of the jump.
