Joule-Thomson inversion temperature (source code)

= Joule-Thomson inversion temperature
{c}
{title2=$T_{\rm inv}(p)$}

A <Joule-Thomson inversion temperature> is a <temperature> at which the <Joule-Thomson coefficient> is zero at a specified <pressure>. There can be more than one such <temperature> at that <pressure>; distinguish the upper and lower branches from a maximum or a dilute-gas limiting value.
