Repeat Problem 14.3 if the side slope is 45°.
Problem 14.3
A drainage structure for an industrial park has a trapezoidal cross-section similar to that shown in Fig. 14.2(c). The bottom width is 3.50 ft and the sides are inclined at an angle of 60° from the horizontal. Compute the hydraulic radius for this channel when the fluid depth is 1.50 ft.
