The simplest estimate estimate (also called Linear Blending Rule) of Pseudo-Critical Point
is the mole fraction weighted average of the Сritical Temperature (Tc) and Critical Pressure (pc) of mixture components (which are pure substances) :LaTeX Math Inline body --uriencoded--( T_%7Bpc%7D, \, p_%7Bpc%7D )

In case the fluid composition is not known one can use some popular empirical Pseudo-Critical Point Correlations to assess the Pseudo-Critical Point.
