1. A trapezoidal channel with a bottom width of 4.00 feet and side slopes of 2 horizontal to 1 vertical conveys a discharge of 300 cfs. If the depth of flow is 2.25 feet, what is the Froude number? Is the flow subcritical or supercritical?
2. A trapezoidal channel with a bottom width of 10.0 feet and side slopes of 2 horizontal to 1 vertical conveys a discharge of 450 cfs. If the depth of flow is 2.50 feet, what is the Froude number? Is the flow subcritical or supercritical?
