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...
