Definition

quotient of isothermal compressibility (ISO 80000-5: Thermodynamics) of a gas and that of an ideal gas, expressed by

$Z = \frac{p}{ρ R_{s} T}$ ; where

$p$ :: is pressure (ISO 80000-4: Mechanics),

$ρ$ :: is mass density (ISO 80000-4: Mechanics),

$R_{s}$ :: is specific gas constant (ISO 80000-5: Thermodynamics), and

$T$ :: is thermodynamic temperature (ISO 80000-5: Thermodynamics)

quotient de la compressibilité isotherme (ISO 80000-5: Thermodynamics) d'un gaz par celle d'un gaz parfait, exprimé par:

$Z = \frac{p}{ρ R_{s} T}$ ; où

$p$ :: est la pression (ISO 80000-4: Mechanics);

$ρ$ :: est la masse volumique (ISO 80000-4: Mechanics);

$R_{s}$ :: est la constante massique du gaz (ISO 80000-5: Thermodynamics); et

$T$ :: est la température thermodynamique (ISO 80000-5: Thermodynamics)
