Gas compressibility factor

gas compressibility factor is the ratio of the Real Gas volume to the Ideal Gas volume, which is a measure of the amount that the gas deviates from the perfect behavior.

 z = \frac{Actual\ volume\ of\ gas\ at\ specified\ T\ and\ P}{Ideal\ volume\ of\ gas\ at\ same\ T\ and\ P} [1]

Discussion

Dranchuk correlation is the default correlation for the gas compressibility factor in the PVT tool.
