the pressure of a multi-component fluid is expressed as a function of volume, temperature and amount of substance. The mathematical transformations can be applied to any equation of state with the form p(V,T,n), i.e.

The van der Waals equation of state has been added to the group Loners and is used to illustrate a large variety of calculation procedures for many thermodynamic parameters and properties. The programs are provided with a Graphical User Interface (GUI) and are adapted to new operating systems, including MacOS, Windows and Linux. The computer package FLUIDS (Bakker 2003) has been revised to calculate fluid properties in pores and inclusions.
