Subcritical, uniform flow of water occurs in a rectangular, horizontal channel with a width of 5.0 m. The flow has a depth of 2.0 m and a flow rate of 5.0 cu.m/s. The flow encounters a 0.25 m rise in the channel bottom. What is the new normal depth? Is the flow above the rise subcritical, critical or supercritical? Assume frictionless flow
