An artificial open channel is to be designed as a rectangular cross-section as shown below. The hydraulics engineer is given that the total wetted perimeter must be equal to 8.0 m. The channel must also be able to carry a total flowN capacity of 20 m^3/s with the corresponding average velocity of 3.4 m/s. Determine the width (b) and depth of flow (h) that satisfy these constraints, if the depth is not to exceed 1.5 m.
