A vertical sluice gate in a long rectangular channel 5 m wide is lowered to produce an opening of 1.0 m. Assuming that the free flow conditions exist at the vena contracta downstream of the gate verify that the flow in the vena contracta is supercritical when the discharge is 15 m3/s and determine the depth just upstream of the gate, Cv = 0.98; Cc = 0.6. Take the upstream velocity energy coefficient to be 1 and that at the vena contracta to be 1.2. (ans. 2.09 m)

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...

A 5-m wide rectangular channel with two reaches, each with a different slope, conveys 40m3/s of water. The channel slope for the first reach is 0.0005 and then a sudden change to a slope of 0.015 so that critical flow occurs at the transition. Determine the depths of flow at locations 10 m, 20 m and 30 m upstream of the critical depth. The Manning’s n for the channel is 0.015.
