Physical Property Correlation	User-defined vapor properties can be No phase change gases based on temperature correlation data or Pure Newtonian via various equations of state (Peng-Robinson, Lee-Kesler, and Benedict-Webb-Rubin-Han-Starling).
Pressure Drop Correlation	FluidFlow uses a calculation procedure that solves the conservation equations and an equation of state for small pressure loss increments. This means FluidFlow obtains a much more rigorous and accurate solution reflective of actual plant performance. Available equations of state include Benedict-Webb-Rubin-Han-Starling, Peng-Robinson, and Lee-Kesler. Using the EOS the gas thermophysical properties such as enthalpy and density are calculated as the gas accelerates. FluidFlow makes no assumptions of gas ideality or adiabatic flowing conditions.

The method is a development of a paper originally published in The Chemical Engineer – Relief Line Sizing for Gases Part1 and 2. Dec 1979 – HA Duxbury.
