Parachor software estimates the surface tension of binary liquid mixtures with the Parachor method using the Peng-Robinson equation of state for density calculation, two component-specific constants called Parachors, and an exponent parameter.
The estimated surface tension dependence on temperature and concentration can be saved in the form of a lookup table implemented as a C function.
The list of the available binary mixtures includes:

• diethylether - nitrogen
• propane - carbon dioxide
• butane - carbon dioxide
• isobutane - carbon dioxide
• chlorodifluoromethane - carbon dioxide

Installation

The parachor software is implemented in Python and it requires several dependencies installed in the system: python, numpy, matplotlib, python-qt4, texlive, dvipng. On an Ubuntu system, the dependencies are installed by:

  sudo apt-get install numpy python-matplotlib 
  python-qt4 texlive texlive-latex-extra dvipng

After unzipping the downloaded archive, the program is run by:

  python parachor.py
