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 channel
c. Is the flow supercritical or subcritical? _______

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

Water discharging into a 12-m-wide rectangular horizontal channel from a sluice gate is observed to have undergone a hydraulic jump. The flow depth and velocity before the jump are 0.9 m and 9 m/s, respectively. Determine (i) Froude number before the hydraulic jump. Is it subcritical, critical, or supercritical flow? (4 points) (ii) the flow depth and the Froude number after the jump. Is it subcritical, critical, or supercritical flow? (9 points) (iii) the head...

A rectangular channel needs to be designed to carry a maximum carrying capacity of 300 cfs flow. The channel base width should be 9 ft. The channel should be designed with a longitudinal slope of 0.005. Treat Manning’s n as 0.012. A free board of 3 ft is needed for a safe channel. Design the channel. (you need to decide how deep it should be)
