Water flows in a rectangular concrete channel that is 10 m wide and has a slope of 0.005. The depth of the uniform flow in the channel (y1) is 450 mm and the discharge per width of the water is 2.2 m2/s. The downstream channel is smooth, and a hydraulic jump is forced to form in the channel by installing a sill. Calculate: (i) the depth and velocity of the water downstream of the hydraulic jump; (ii) the difference in...
