An 8 ft. wide and 1000 ft. long prismatic rectangular channel is carrying a flow of 13 cfs
An 8 ft. wide and 1000 ft. long prismatic rectangular channel is carrying a flow of 13 cfs. The channel has a slope of 0.001 ft/ft and Manning's n is 0.035. The depth of water in the channel is 1.25 ft. a. Another engineer computed the normal depth in the channel to be 1.25 ft, which is the existing depth of flow. Check that computation to see if it correct (show all work) b. Compute the critical depth of flow in the...

2. A 2.5 m wide rectangular channel conveys m wide rectangular channel conveys water at a normal depth of 2 m. In a part of the channel, the channel width is expanded to 5 m. The local energy loss due to this expansion is about 10% of the upstream velocity head. If the channel slope is 0.03% and the Manning roughness coefficient is about 0.012, calculate the water depth over this transition and show the situation with a simple sketch.

Supercritical, uniform flow of water occurs in a 5.0 m wide, rectangular, horizontal channel. The depth of flow is 1.5 m and the flowrate is 45 cu.m/s. The flow encounters a 0.25 m rise in the channel bottom. What is the new normal depth? Is the flow after the rise subcritical, critical or supercritical? Assume frictionless flow
