IAPWS IF97-Rev

[maikksmt]

Hello, how do you feel about implementing the Revised Release on the IAPWS Industrial Formulation 1997 for the Thermodynamic Properties of Water and Steam, August 2007 [IAPWS R7-97(2012)] and plotting the results of a change of state, maybe even drawn in a Mollier diagram?

Hi @maikksmt. Thanks for your interest.

I found a python implementation of IAPWS IF 1997 here. Does that meet your needs?

I agree that I need a Mollier diagram. :o)

The iapws library is good, but it does not have a feature to plot anything. I have my own code that contains the iapws standard and would like to plot the results and state changes into a Mollier diagram on a web interface. Unfortunately, I do not know how to realize such a plot. Maybe I should use Coolprop, but that's pretty big and a bit too huge for my application.

I added a draft Mollier diagram (labels still need to be added). The code is fairly complicated. CoolProp presumably does much of the calculations behind the scenes.
