Throttling and Joule-Thomson Expansion: Screencasts
Shows the temperature change of non-ideal gases through an adiabatic throttle due to Joule-Thomson expansion.
We suggest you list the important points in this screencast as a way to increase retention.
Describes the Joule-Thomson coefficient and calculates how much liquid forms when a high pressure gas undergoes a J-T expansion. The Peng-Robinson equation of state spreadsheet can be found on www.chethermo.net/software.

Important Equations:
Steady-state energy balance for an adiabatic throttle:
\[0= \Delta H\]
where \(\Delta H\) is the change in enthalpy for the fluid from inlet to outlet.
Joule-Thomson coefficient:
\[\mu = \left( \frac{\partial T}{\partial P} \right) _H\]
Note that the same symbol \(\mu\) is used for the J-T coefficient and for chemical potential.
