Compressibility factor values are usually obtained by calculation from equations of state (EOS), such as the virial equation which take compound-specific empirical constants as input. The improved function will be up as soon as the File Exchange administrators approve it. Similarly the input of the gas name is limited in that if someone doesn’t capitalize the name correctly or misspells it, the code won’t run.

It uses the Van Der Waals equation instead of more accurate equations like Redlich-Kwong Equation of State or the Dieterici Equation of State. sulfur hexafluoride, Note: The Van der Waals equation is an improvement of the ideal gas law, above the critical temperature, and is also qualitatively reasonable below the critical temperature, but it is almost never appropriate for rigorous quantitative calculations. Accelerating the pace of engineering and science. The unique relationship between the compressibility factor and the reduced temperature, Tr, and the reduced pressure, Pr, was first recognized by van der Waals in 1873 and is known as the two-parameter principle of corresponding states.
