This application uses the Darcy-Weisbach equation to calculate liquid velocity in a pipe. The Darcy-Weisbach equation describes the relationship between the pressure loss and liquid velocity in a pipe.

There are 76 types of pipe materials to choose from.
There are 58 types of liquids to choose from.
And there are a variety of pipe sizes up to a diameter of 84 inches (2100 mm).
