Reduced Specific Volume

Reduced specific volume, abbreviated as \(\upsilon_r \) (Greek symbol upsilon), also called pseudo-reduced specific volume, of a fluid is ratio of the specific volume of a substance's critical pressure and temperature.

 

Reduced Specific Volume formula

\(\large{  \upsilon_r = \frac {\upsilon \; p_c}{R \; T_c}   }\)

Where:

\(\large{ \upsilon_r }\)  (Greek symbol upsilon) = reduced specific volume

\(\large{ p_c }\) = critical pressure

\(\large{ T_c }\) = critical temperature

\(\large{ \upsilon}\)  (Greek symbol upsilon) = specific volume

\(\large{ R }\) = universal gas constant
