Specific volume

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}{ ho}

where, V is the volume, m is the mass and ho 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.
