Do you end up with the same entropies at the ends of the compression processes when you integrate? If the process is truly isentropic, I suppose you should. Or your...

Another thought, the enthalpies and entropies are per kg of dry air, perhaps that is throwing things off too On Thu, Apr 24, 2014 at 4:14 PM, Ian Bell [email protected]...

Lets start off with an even smaller W (say 1e-10) - though I am not sure that is the cause. You are adding such a small amount of water, it...

Interesting. I'll have to take a look and see what is going on. Thanks for the very clear description of the problem. On Fri, Apr 25, 2014 at 1:27 PM,...

Sorry at the moment, no, I am working hard on a new version of CoolProp and haven't had the chance to take a look yet. Can you do a plot...

Interesting. The HAProps definition of the enthalpy is not the same as for the pure fluid - you can see that by reading http://rp.ashrae.biz/page/ASHRAE-D-RP-1485-20091216.pdf . It is not entirely surprising...

The basic problem is that if you read that document, they have terms that are log(psi_w), which is -infinity at psi_w = 0, psi_w being the mole fraction of water...

What files are in c:\ees32\Userlib\COOLPROP_EES ? You did run the installer from http://sourceforge.net/projects/coolprop/files/CoolProp/4.1.2/EES/ right? On Thu, Mar 20, 2014 at 4:15 PM, Ahmedyy [email protected] wrote: > I have one problem...

How about uninstalling COOLPROP_EES using windows install/uninstall, delete the files in c:\EES32\Userlib\COOLPROP_EES, and then reinstall COOLPROP_EES? What version of EES do you use? What operating system? Anything abnormal about your...

I use EES 9.567 on 64-bit Windows 7, are you also on Windows 7? It should just work.
