Froude Number Calculator

Froude Number (Fr):

Flow velocity (v):

Gravitational acceleration (g):

Characteristic Length (L):

How This Is Calculated

$$ Fr = \frac{v}{\sqrt{gL}} $$ where:

Fr = Froude Number (Dimensionless)

v = Flow velocity (m/s²)

g = Gravitational acceleration (m/s²)

L = Characteristic Length (m)

Assumptions

The fluid is incompressible.
Viscosity is negligible.
Steady flow conditions.
Flow is single phase.
Flow depth is uniform.
