Enter the flow velocity, acceleration of gravity, and mean depth into the calculator to determine the Froude number.

Froude Number Calculator

The following equation is used to calculate the Froude number of a gravitational wave.

F = V * Sqrt ( g * h)

  • Where F is the Froude number
  • V is the flow velocity
  • g is the acceleration due to gravity
  • hm is the mean depth

Froude Number Definition

A Froude Number represents the ratio of inertial force to the gravitational force acting on a fluid.
