\kappa_{S}

Definition

negative relative change of volume with pressure at constant entropy:

κ_{S} = - \frac{1}{V} {(\frac{\partial V}{\partial p})}_{S}

where $V$ is volume (ISO 80000-3: Space and time), $p$ is pressure (ISO 80000-4: Mechanics), and $S$ is entropy (entropy)

opposé de la variation relative de volume en fonction de la pression à entropie constante:

κ_{S} = - \frac{1}{V} {(\frac{\partial V}{\partial p})}_{S}

où $V$ est le volume (ISO 80000-3: Space and time), $p$ est la pression (ISO 80000-4: Mechanics) et $S$ est l'entropie (entropy)
