A trapezoidal channel has n = 0.022 and S0 = 0.0003 and is made in the shape of a half-hexagon for maximum efficiency. What should the length of the side of the hexagon be if the channel is to carry 225 ft3/s of water? What is the discharge of a semicircular channel of the same cross-sectional area and the same S0 and n?
