Water flows uniformly at a depth (y1) of 0.8 m (2.6 ft) in a rectangular concrete channel (n = 0.015), 10.0 m (32.8ft) wide on a slope of 0.05. A sill is installed in the channel to cause a hydraulic jump to form. Compute the height of the hydraulic jump (y2) and the energy lost in the jump expressed as a percent of the energy at 1.
