Question: 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

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.

х W- х W- A = WD + XD WP = W + 2L (c) Trapezoidal channel

W- W- A = WD + XD WP = W + 2L (c) Trapezoidal channel
