The symmetrical trapezoidal channel shown below has a Manning's value of n = 0.018 and a longitudinal slope of 0.003. A flow of 13.2m³/s is measured in this channel. y 3.2m a) (5 minutes) Derive formulas for the Area and Wetted Perimeter of the flow in terms of the depth (y) b) (4 minutes) Verify that the normal depth of flow is approximately 1.22m c) (3 minutes) Determine if the flow is subcritical or supercritical by calculating the Froud number.
