Compute the hydraulic radius for a trapezoidal channel with a bottom width of 150 mm and with sides that pitch 15 mm horizontally for a vertical change of 10 mm. That is, the ratio of X D in Fig. 14.2 (c) is 1.50. The depth of the fluid in the channel is 62 mm.

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

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