Froude Number Calculator

Calculate the Froude Number for any channel using:
\[ \mathrm{Fr} = \frac{V}{\sqrt{g\,d}} \]

* Enter the flow velocity \(V\) (ft/s) and the hydraulic depth \(d\) (ft).

Step 1: Enter Parameters

Flow Velocity, \(V\) (ft/s):

Example: 5 ft/s

Hydraulic Depth, \(d\) (ft):

Example: 2 ft
