Specific Gas Constant

Written by Jerry Ratzlaff on . Posted in Constants

Specific gas constant, abbreviated as R, deals with the universal gas constant which is equal to 8.314 joules per Kelvin.

specific gas constant formula

 $$\large{ R = \frac{ R^* }{ MW } }$$

Where:

 Units English Metric $$\large{ R }$$ = specific gas constant $$\large{\frac{lbf-ft}{lbm-R}}$$ $$\large{\frac{J}{kg-K}}$$ $$\large{ MW }$$ = molecular weight $$\large{\frac{lbm}{lbmol}}$$ $$\large{\frac{kg}{kmol}}$$ $$\large{ R^* }$$ = universal gas constant $$\large{ \frac{lbf-ft}{lbmol-R} }$$ $$\large{ \frac{J}{kmol-K} }$$
