A trapezoidal channel, bottom width 6 m and side slopes 1/1, flows 1.2 m deep on a slope of 0.0009. For a value n=0.025, the uniform discharge is most nearly: A. 9.81 m3/s B. 4.37 m3/s C. 12.63 m3/s D. 16.72 m3/s

A rectangular concrete channel (n = 0.014) has a bottom width of 5.05 m and a longitudinal slope of 0.002. Compute the discharge rate and velocity for a water depth of 2.34 m. Compute normal depth, critical depth, and critical slope for a discharge of 6.67 m³/s.

In a rectangular open channel, 2.0 m wide, water flows at a depth of 0.8 m. It discharges over an aerated sharp crested weir over the full width, with depth over weir crest being 0.25 m/ Cc = 0.61. Adjusting for velocity head of approach, what would be the discharge through the channel? √29= 4.43 units.

Water flows in a concrete rectangular channel (n = 0.013) that is 12.0 m wide and water depth of 2.5 m. The channel slope is 0.0028. Calculate the water velocity V and flow rate Q.
