Super-critical Fluid Compressibility Factor Z , for Intermediate
![](https://mychemengmusings.files.wordpress.com/2018/03/supercrirical-fluid-compressibility-z-graph.jpg?w=584)
In this post a correlation for the direct calculation of the compressibility factor Z of fluids at super-critical conditions, i.e. temperatures and pressures above the critical point, is presented. The correlation is based on the data published by Lydersen et al. The new correlation is suited to be used in a single "cell" of an…
