Question
In a circular channel 3.0 meters in diameter, flowing over half full, the water surface
width is 1.268 meter in length.
a. Compute the hydraulic radius.
b. The channel is laid on a grade of 16.10 meters per mile; compute its discharge
using Manning’s formula with n = 0.030.
c. For flow as in (b), compute the C value in the Chezy formula.
d. Using C in (c), and for flow as in (b), compute the value of Kutter’s n in the
Kutter’s C formula. Simplify your solution, no solution by calculator or shift
solve.
e. Compute the maximum velocity that may occur for the given circular channel
using n as in (d) and Manning’s formula
