PR says air at amb conditions is a liquid!, SRK is ok:
.21 mol% o2
.79 N2
1 bar
20 C

Re: liquid air @ AMB
It is super critical (so neither a liquid nor a vapor), and the decision to call it a liquid is rather unfortunate. I will check why this is. As a result of this, the density routine that is invoked is not that of the equation of state (which is the density routine for the vapor phase), but the default selected for the liquid phase, which is COSTALD, which is of course completely off.

Should be fixed now. Please run CUP to get the update.

Thank you for reporting the issue.

Re: liquid air @ AMB
Thanks for the fix,
I wouldn't call air at ambient conditions supercritical though; it is above the critical critcal T of -140C but well below critical p of 38 bar thus still a gas.

Re: liquid air @ AMB
It is indeed below the critical pressure.
