Uniform water flow in a wide brick channel of slope 0.02 degrees moves over a 10-cm bump. A slight depression in the water surface results. If the minimum water depth per meter of width Then, again a...
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
