A trapezoidal channel with a bottom width of 5 m and side slopes t = 2 runs on a slope of 0.0005 and carries a discharge of 50
/s at normal depth. Take Manning's n as 0.021 (metric).

a. What is the specific energy of the flow in the channel?

b. Is the flow subcritical or supercritical?

c. What is the alternate depth to the normal depth?

d. What is the critical depth in the channel?
