where
Z | Compressibility factor | p_c | |
p | Gas pressure | T_c | Сritical temperature |
p_r = p/p_c | Reduced pressure | ||
T | Gas temperature | T_r = T/T_c | Reduced Temperature |
R | Gas constant | \omega | accentric factor |
Once compressibility Z-factor
Z(p, T) is known the gas density
\rho can be calculated as:
(6) | \rho(p, T) = \frac{1}{Z(p,T)} \cdot \frac{M}{R} \cdot \frac{p}{T} |
where
