Problem 15.29 (GO Multipart) Part 1 Incorrect. Did you use the trigonometric relations to calculate the flow area? The area is trapezoidal in shape and can be determined by thinking of it as two triangular areas and a rectangular one Did you use the continuity equation? The discharge in a trapezoidal channel is 8 m3/s. The bottom width of the channel is 2.7 m, and the side slopes are 1 vertical to 1 horizontal. If the depth of flow is 0.67 m, is the flow supercritical or subcritical? (a) What is the flow area (cross-sectional area)? m2 (b) What is the average velocity in the channel? m/s Click if you would like to Show Work for this question: Opn Show Work
