Chézy Flow Calculator

Compute open-channel velocity v = C·√(R·S) (Chézy formula).

Input Data

Chezy Coefficient
Hydraulic Radius
m
Slope

Results

v = C·√(R·S).
1.118m/s

At a glance:v = C·√(R·S) (Chézy). Complements manning-flow and hydraulic-radius.

Formula

v = C·√(R·S).

$$v = C\sqrt{R\,S}$$

How to Use

  1. Enter C, hydraulic radius and slope.
  2. The tool returns velocity.

Case Studies

C=50, R=1, S=0.01

v = 5 m/s.

FAQ

C vs Manning n?

C = R^(1/6)/n (Manning relation).
