1. A trapezoidal channel with a bottom width of 5.0 feet and side slopes of 2 horizontal to 1 vertical has a discharge of 150 cfs. What is the critical depth?

2. A rectangular channel with a width of 6.0 feet conveys a discharge of 115 cfs. If the depth of flow is 3.0 feet, what is the velocity? What is the Froude number? Is the flow subcritical or supercritical?
