Gas Pipe Sizing

This program has been written to calculate with different formulas for compressible gas flow in pipes. Fluid hydraulics information is taken from

Gaz Akış

Enter the pressure value as absolute pressure. In calculation; Atmospheric pressure is accepted as 1.013 bar, outdoor temperature 15 °C in the SI unit system, and 14.696 psi, 60 °F in the USCS unit system.
absolute pressure = gauge pressure + atmospheric pressure.
