    solving Joule-Thompson pressure drop

    Ok- so how would I use that in my case? I don't know enthalpy.

    solving Joule-Thompson pressure drop

    Yes- I couldn't solve the equation at the wikipedia site. First, going thru the regulator we have P1=600psi; P2=350; T1=60 degrees F; T2 unknown; V2=unknown and V1=unknown. then I have the same info but going from P1=900psi to P2=350psi. Too many variables.

    solving Joule-Thompson pressure drop

    I need help solving a problem, probably with the Joules- Thompson effect. I know that if I have a pressure reducing valve (regulator), when I increase the inlet pressure by 300 psi, for the same outlet pressure, I get a temperature drop of 21 degrees F. I need the equation showing this. I'm...
