Froude Number

Froude Number is the ratio of inertial force to gravitational force. It is used for wave and surface behavior for mixed natural and forced convection.

FORMULA

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

Where:

\(Fr  \) = Froude Number

\(v  \) = flow velocity

\(g  \) = gravitational acceleration

\(h_m \) = mean depth

Solve for:

\(v =  Fr \sqrt { g  h_m }  \)

\(g =  \frac {v^2}  { h_m   {Fr}^2  }    \)

\(h_m =  \frac {v^2}  { g  {Fr}^2  }  \)
