Manning's Equation (Civil Engineering) Formula
Calculates the average velocity of water flowing in an open channel.
Formula
v = (1/n) · R^(2/3) · S^(1/2)
Discipline: Civil Engineering. Result unit: m/s.
Variables and units
- v — Velocity (m/s): Average flow velocity
- n — Manning Coefficient: Manning's roughness coefficient
- R — Hydraulic Radius (m): Hydraulic radius
- S — Slope (m/m): Slope of the channel
