Definition

change of thermodynamic temperature with respect to pressure in a Joule-Thomson process at constant enthalpy:

μ_{JT} = {(\frac{\partial T}{\partial p})}_{H}

where $T$ is thermodynamic temperature (thermodynamic temperature), $p$ is pressure (ISO 80000-4: Mechanics) and $H$ is enthalpy (enthalpy)

variation de la température thermodynamique en fonction de la pression dans un processus de Joule-Thomson à enthalpie constante:

où $T$ est la température thermodynamique (thermodynamic temperature), $p$ est la pression (ISO 80000-4: Mechanics) et $H$ est l'enthalpie (enthalpy)
