Reduced Specific Volume

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

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

\(\large{  \upsilon_r = \frac {\upsilon \; p_c}{R \; T_c}   }\) 
Symbol English Metric
\(\large{ \upsilon_r }\)  (Greek symbol upsilon) = reduced specific volume \(\large{\frac{ft^3}{lbm}}\) \(\large{\frac{m^3}{kg}}\)
\(\large{ p_c }\) = critical pressure \(\large{\frac{lbf}{in^2}}\) \(\large{Pa}\)
\(\large{ T_c }\) = critical temperature \(\large{ F }\) \(\large{ K }\)
\(\large{ \upsilon}\)  (Greek symbol upsilon) = specific volume \(\large{\frac{ft^3}{lbm}}\) \(\large{\frac{m^3}{kg}}\)
\(\large{ R }\) = universal gas constant \(\large{ \frac{lbf-ft}{lbmol-R} }\) \(\large{ \frac{J}{kmol-K} }\)
