Homework Statement
I need to know what happens if compressed air from a vessel at room temperature is throttled from 450 bar to 2 bar.
Homework Equations
I know Joule-Thomson effect (http://http://en.wikipedia.org/wiki/Joule-Thomson_effect" ) deals with this, but I'd need it explained a bit more clearly, like what volume is in the equation and under what circumstances is it true.
The Attempt at a Solution
I know air will cool down when throttled, but at certain pressure and temperature it will liquefy. Will it liquefy during throttling?
What about work that was lost due to entropy change? If this system is isothermal, that is, the throttled air is reheated to initial temperature, ...
d0h, there's too many things in my head. I hope you know what I don't know I don't know.
