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 default Material, Steel. Calculate for 2”
Pipe with a Flow Rate of 4 gallons per minute
and then convert to different dimensional units.

Using values above, add the Run (Length) to calcu-
late the Pressure Loss over the length of the pipe.
