Consider channels of rectangular cross section carrying 100 cfs of water flow. The channels have a slope of 0.001. Determine the cross-sectional areas required for widths of 2 ft , 4 ft , 6 ft , 8 ft , 10 ft , and 15 ft . Plot A versus y/b, and see how the results compare with the accepted result for the best hydraulic section. Use the Manning equation, with unfinished concrete.
