The flow rate in a 10.0 ft wide and 3 ft deep rectangular channel is 225.0
/s. Is this flow subcritical or supercritical?

The discharge in a trapezoidal channel is 200
 ls. The channel has a bottom width of 5.0 ft and a side slope of 3:2. The depth of flow is 4 ft. Determine the Froude number and Reynolds number (take the kinematic viscosity, v, as 1.059 X
/s). What is the regime of the flow?
