5. A uniform flow of 110,000 ft³/s is measured in a natural channel that is approximately rectangular in shape with a 2650-ft width and 17.5 ft depth. The water-surface elevation drops 0.37 ft per mile. Based on the computed Manning coefficient, n, characterize the type of natural channel observed. Also compute the Froude number and determine whether the flow is subcritical or supercritical.
