Problem 3. A 3 m wide channel with a rectangular cross-section is carrying a flow with flow rate Q = 9 m/s and specific energy E = 2 m. What are the possible flow depths of this flow and the corresponding velocities? Calculate the Froude number associated with each flow depth.

Determine the critical flow depth and the specific energy related to the critical flow depth for a volumetric flow rate of 5.0 cubic meters per second in a triangular channel with a slope coefficient of 0.5

A triangular channel with most efficient proportion discharges water at the rate of 1m^3/s. Assuming n= 0.018 and S = 0.0021, calculate the normal depth of flow in meters.
