Specific volume

Specific volume ($$v$$) is the volume occupied by a unit of mass of a material. It is equal to the inverse of density. Specific volume may be expressed in $$ \frac{m^3}{kg} $$, $$ \frac{ft^3}{lbm} $$ or $$ \frac{mL}{g} $$.


 * $$ v = \frac{V}{m} = \frac{1}{\rho} $$

where, $$V$$ is the volume, $$m$$ is the mass and $$\rho$$ is the density of the material.

For an ideal gas,
 * $$v = \frac{R T}{P M}$$

where, $$R$$ is the specific gas constant, $$M$$ is the molar mass, $$T$$ is the temperature and $$P$$ is the pressure of the gas.

Specific volume may also refer to molar volume.
