# Compressibility Factor

Compressibility factor, abbreviated as z, a dimensionless number, also called compression factor or gas deviation factor, corrects for deviation from the ideal gas law to account for the real gases behavior.

\(\large{ Z }\) = compressibility factor | \(\large{ dimensionless }\) | |

\(\large{ n }\) = number of moles | \(\large{dimensionless}\) | |

\(\large{ p }\) = pressure | \(\large{\frac{lbf}{in^2}}\) | \(\large{Pa}\) |

\(\large{ R }\) = specific gas constant | \(\large{ constant }\) | |

\(\large{ T }\) = temperature | \(\large{F}\) | \(\large{K}\) |

\(\large{ V }\) = volume | \(\large{ft^3}\) | \(\large{m^3}\) |
