Which one is the formula for sewer design?

Chezy’s formula where V= is the mean velocity [m/s], C= is the Chézy coefficient [m½/s], R= is the hydraulic radius (~ water depth) [m], i= is the bottom slope[m/m].  Constant (C) is very complex. Depends on size, shape and smoother roughness of the channel, the mean depth etc.
