Froude Number Calculator

Froude Number refers to the dimensionless number which is a ratio of a characteristic velocity to a gravitational wave velocity. In short, the Froude number is defined as the ratio of a body's inertia to gravitational forces. It is expressed by the symbol 'Fr'. The Froude Number is used in hydrodynamics to indicate how well a particular model works in relation to a real system.
Froude Number Calculator
I want to calculate
Flow Velocity (V): m/s
Acceleration of Gravity (g): m/s2
Mean Depth (hm): m
Froude Number (F):
Formula
Froude Number :
F = V/√ ghm

Flow Velocity :
V = F√ ghm

Acceleration of Gravity :
g = V2/ hmF2

Mean Depth :
hm= V2/gF2

Where,
F = Froude Number,
V = Flow Velocity,
g = Acceleration of Gravity,
hm = Mean Depth.

This Online Advanced Froude Number Calculator is useful in calculating the Froude Number by putting the values Flow Velocity (V), Acceleration of Gravity (g) and Mean Depth (hm) and apply the formula.

Example:
Calculate the Froude Number for the given details.
Flow Velocity (V) = 20 m/s
Acceleration of Gravity (g) = 15 m/s2
Mean Depth (hm) = 10 m

Solution:
Apply Formula:
F = V/ √ ghm
F = 20/√15*10
F = 1.63
Froude Number (F) = 1.63
