A hydraulic jump takes place in a triangular channel of vertex angles 90°, as shown in figure. The discharge is 1 m³/s and the pre-jump depth is 0.5 m. What will be the post-jump depth? (Take g = 9.81 m/s²) 90° las
A rectangular channel is 4 m wide, and it reduces to 2 m through a hydraulic structure. Assuring the transition to be horizontal and the flow to be frictionless determine the water surface elevations upstream of the constriction when the specific energy at the constriction is 6 m. Assume choking occurs, hence critical flow equations are applicable. Note: Hand written solution is not allowed.

13. (LAB) A discharge of 25 m³/s is passing in a rectangular channel of bed width 8.0 meters and water depth 3.0 meters. The channel bed width is gradually contracted from 8.0 meters at section (1) to 6.0 meters at section (2). In the contraction zone, a smooth hump is placed in the channel in which the bed level is gradually increased by 1.00 m. Determine: (i) The change in water levels, (ii). The minimum height of hump so that y2 = ye, and (iii) The change in water levels if the hump height is 1.50 meter.
1. A channel of width 5m has a sluice gate as shown below, which forces the upstream flow to a deep state and the downstream flow to a shallow state. If the flow Q = 10m/s and the water depth at section B yB = 0.5m, estimate the water depth, velocity and velocity head at section A. Assume that there is no variation in velocity over the cross-section and neglect energy losses. 2g YA 2g H energy datum Ув — 0.5m level section A section B
A trapezoidal channel has a bottom width of B = 5 m, sidewall slope of 1V:1H, and bed slope of S=0.004.
