What Does A Positive Joule Thomson Coefficient Represent? Expansion of most real gases causes cooling when the Joule–Thomson coefficient is positive and the gas temperature is below the inversion temperature. What does Joule-Thomson coefficient represent? Joule-Thomson coefficient is defined as the rate of change of temperature with pressure during an isenthalpic process or throttling process.

How Do You Calculate Joule-Thomson Effect? The Joule-Thomson equation is μ = (T1 – T2) / (P1 – P2) where μ is the Joule-Thomson coefficient, T1 is the initial temperature, T2 is the final temperature, P1 is the initial pressure and P2 is the final pressure. Rearranging yields -μ x (P1 – P2) + T1
