A triangular channel (side slope 1.5) carries 50 cfs. (1) Develop and plot the specific energy curve (2) Compute the critical water depth and minimum specific energy (3) Compute the alternate depth of 4.5 ft (4) Compute the Froude number for a water depth of 2.5 ft (5) If the water depth is 1.0 ft, is the flow critical, subcritical, or supercritical? Why?
