Dear colleagues,
I'm confused because I thought that kappa = cp /cv generally.
Now I found in different property-tools, that for example water-steam 30barA, 245°C,cp=3.1992, cv=2.1134, cp/cv=1.513 BUT kappa=1,2804.
Why that? How can I get to this kappa-value. In my EXCEL-tools I use the water97_v13.xla which provides cp and cv only.
Thanks!
Johann
