Pressure loss
If you know Flow/Velocity, Pipe Size and Length,
you can calculate Pressure Loss. If no Run
Length is entered, Pressure Loss per foot is
calculated. For this example we will use the de-
fault Material, Plastic. Calculate for 2” Pipe with
a Flow rate of 4 gallons per minute and then
convert to different dimensional units.

Using the values above, you can then add the
Run (Length) to calculate the Pressure Loss
over the length of the pipe.
