Froude Number

Written by Jerry Ratzlaff on . Posted in Dimensionless Numbers

Froude number, abbreviated as Fr, is a dimensionless number which is the ratio of inertial force to gravitational force.  It is used for wave and surface behavior for mixed natural and forced convection.

formulas that use Froude number

\(\large{ Fr =  \frac { v }  { \sqrt { g \; h_m }  }  }\)   

Where:

\(\large{ Fr  }\) = Froude number

\(\large{ g  }\) = gravitational acceleration

\(\large{ h_m }\) = mean depth

\(\large{ v  }\) = velocity of flow
