A vertical sluice gate spans the full width of a rectangular channel 6.0 m wide. If the downstream depth is 1.2 m and the upstream depth is 6.0 m,what will be the flow if the upstream depth is 6m

A concrete-lined channel must be designed to convey a discharge of 500 m3/s. The bedslope of the channel must be 11 degrees due to the topography of the area. For the given discharge, design a trapezoidal channel with the best hydraulic section.

A rectangular channel has a width of 2.0 m and carries a flow of 3.0 cms. If the depth of flow at a section is 0.35 m, calculate 1) Specific energy at that section, 2) flow depth alternative to the existing depth, 3) Froude number at the alternative depth, and 4) critical depth. Ans: (hint: consider C.E and S.E.)

The flow in a long 4.0 m wide rectangular channel is 8.0 m¾. The normal depth of the flow is 1.5 m. If at a certain section P the depth of flow is 1.2 m, the depth of flow downstream of section P would be

The flow rate of water in a 3-m-wide horizontal open channel is being measured with a 0.25-m-high sharp-crested rectangular weir of equal width. If the water depth upstream is 0.9 m, the flow rate of water is(a) 1.75 m3/s (b) 2.22 m3/s (c) 2.84 m3/s(d) 3.86 m3/s (e) 5.02 m3/s

A 6.0 m rectangular channel carries a of 30 m³/s at a depth of 2.5 m. the channel width that produces discharge Determine the critical depth.

A triangular channel has a vertex angle of 90o and carries a flow at critical depth of 0.3m. The discharge in the channel is? (a) 0.11 m3/s (b) 0.21 m3/s (c) 0.31 m3/s (d) 0.41 m3/s
