# .Annex60.Media.Air.isothermalCompressibility

Isothermal compressibility factor

## Information

This function returns the isothermal compressibility coefficient. The isothermal compressibility is

κT = -1 ⁄ v (∂ v ⁄ ∂ p)T = -1 ⁄ p,

where v is the specific volume, T is the temperature and p is the pressure.
