I would like to announce a library that aims at computing the water properties. The formulas are taken from http://iapws.org. For now, I have implemented
- the technical report R2-83 for water properties at their critical points.
- the technical report G7-04 for gas solubility
I plan to implement the technical report R797 for the thermodynamic properties of water and steam (industrial formulations).
There is a complete C API and a python wrapper with binaries on pypi. The library integrates with the Fortran Package Manager.
