LAB No. 4: CRITICAL FLOW

Derive the formula for the critical slope S_c in a prismatic channel, starting with the Manning equation:
Q = (k/n) A R^2/3 S^1/2
in which k = 1 in SI units, and k = 1.486 in U.S Customary units.
Derive the formula for the critical slope S_c in a prismatic channel, starting with the Chezy equation:
Q = C A R^1/2 S^1/2
