Problem 6. A circular conduit carries 400 cfs when the flow velocity is 10 ft/s at...
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...
4. (10 marks) Given a flow of 100 cfs in a rectangle channel with 6 ft. base, Manning roughness coefficient 0.01, and the slope is channel is 1.5%; what is the normal depth and velocity of flow and what is the critical depth and velocity of flow? Is the flow subcritical or supercritical and why (provide a graphical solution on an appropriate chart)?
0.020) to carry a flow of200 10. Determine the required diameter do of a circular corrugated metal culvert (n cfs. The length of the culvert is 150 feet. The slope of the culvert is 0.003 ft/ft. A bell mouth entrance in a concrete headwall is used at inlet. The maximum allowable headwater depth is 2.5do and the tailwater depth y is 1.25do. Identify the flow conditions which govern performance.

6. (FE Practice problem) A flow rate 20 ft3/sec flows through a 30-in.-diameter concrete pipe (Manning's n constant with depth-0.013). The following data is given: Pipe length 800 ft Pipe invert elevation at upstream end of pipe 275.64 ft Pipe invert elevation at downstream end of pipe 270.96 ft The depth of flow (in.) in the pipe is most nearly: Upstream Invert elevation 275.64 t nvert elevation 270.96 A....
