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.

Question
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.
