Hi, I am to calculate the temperature of a pure nitrogen gas after it has expanded;
The initial values is as follows: 460 Bar(g) and 90°C , it will go through a choke valve and expand to atmospheric pressure, this I believe will be an isenthalpic, non-reversible adiabatic process, correct?
Can anyone help me to calculate the joule thomson coefficent for this example, in Kelvin drop per bar ? I can't get it right for some reason,I must be misunderstanding at some point, would be nice to see an example calculated by hand or explained step by step.
I do hope for a fast reply, thx a lot in advance
Best Regards,
Daniel
