Question

A trapezoidal channel flume is made of concrete (n = 0.014) slopes 0.3 ft per 1000 ft.


a. Compute the discharge if the base is 6 ft with ? = 1/√3 and the depth of water is 3 ft.
b. What would be the rate of discharge if the base were 3 ft and the depth of water 6 ft with m = 0.144?
c. Which of the two forms would have the greatest capacity, and which would require less construction material?
