V. Problem Solving 1. A rectangular channel, 20ft wide, carries 400 cfs and discharges onto a 20 ft wide apron with no slope with a mean velocity of 20 fps. What is the height of the hydraulic jump? What energy is lost in the jump? 2. At a certain section of a rectangular channel 10 ft wide, the depth of flow is 2 ft and the flow rate is 400 ft/s. If a hydraulic jump occurs, will it be upstream or downstream of this section? Prove answer using calculation.
