(5) Water flows along a trapezoidal channel with base width B=1.5 m, side slope 1:1 (horizontal to vertical) and depth D=0.7 m. It is controlled downstream by a sharp crested weir that has a crest height of H=2.4 m above the channel bed and a crest width equal to that of the base width.

Water is flowing in a trapezoidal channel with base width B-5' and side slope 3:1 (horizontal to vertical). If the flow depth is D-1.5' what is the flow rate for which the flow is critical?
Water flows steadily along a horizontal open channel of uniform width, over a broad-crested weir. The channel bed upstream from the weir (to the left) is d -0.75m above the channel bed downstream from the weir (to the right), as shown in the figure below. The volume flow rate per unit width is Q 6m2 s-1, and the downstream depth of the water is ћ2-d. Take the magnitude of the acceleration due to gravity as g 10ms-2. d - 0.75...
A trapezoidal channel has a side slope of 1:1 and a bed width of 6.0 m. A hydraulic jump with a height of 0.5 m (i.e. the difference between water surface elevation upstream and downstream of the jump) is encountered in the channel. If the channel has a discharge of 10 m3/s, determine the critical depth in the channel. Plot the momentum curve and determine the flow depth immediately upstream and downstream of the jump.
