Manning's Equation (Hydraulics) Formula
Calculates the velocity of water flow in open channels and pipes.
Formula
V = (1/n) × R^(2/3) × S^(1/2)
Discipline: Hydraulics. Result unit: m/s.
Variables and units
- V — Velocity (m/s): Average velocity of flow
- n — Manning's Coefficient: Manning's roughness coefficient
- R — Hydraulic Radius (m): Hydraulic radius
- S — Slope: Channel slope
