Hello ALL,(adsbygoogle = window.adsbygoogle || []).push({});

I am looking for the derivation of joule thompson effect to show that Uj = (nBTave^-n / Roh(ave) Cp) *Zave

where n = 3.825, B = 5287.Pave.10^1.785G

Pave in KPa(g) and Tave in K

using CNGA approximation.

Can anybody help me in this?

Thanks

Shabbir
