For Natural gas pipeline sizing, see natural gas pipe sizing (Windows OS), or a pocketGas (Android OS).

For Comparessed air pipeline sizing, see compressed air pipe sizing (Windows OS), compressed air ring main pressure drop (WIndows OS).

There are many situations where you want to determine the total pressure drop in series pipes. This app helps you to do that. 

This program solves the pressure drop (Pdrop) in a single or series pipe network using general flow equation. In gas hydraulics, the general flow equation is widely used. Elevation change is ignored.

Important to note: This program is designed with one set of units system for all calculations. For input simplicity, built-in units conversion tools are available.

Various selection and calculation tools are provided, making calculation experience more simulating. They are:

• Flow unit converter, Diameter & Length unit converter, Pressure unit converter.

• Valve & Fitting selection (Equivalent length Le method).

• Common gases selection.

• Pipe material selection.

You can download a sample of the result printout in pdf here.

Example: Nitrogen pipeline sizing

known process data:

Flow = 600 SCFM

inlet pressure = 1000 psig

process temperature = 80 oF

pipe length = 100 ft

pipe material = stainless steel

pipe internal diameter = 1.61 inch

Find the pressure drop.
