Sample Input File
Sample Output File
I developed this tool to have a small, simple and fast calculation for real gas properties. The tool is compiled from FORTRAN code and runs on any DOS or WINDOWS based computer. Input and Output files are ASCII Text. A text editor with overwrite option is suggested i.e. KEDIT or TEXTPAD.
Development of UNIX version or graphic interface is possible upon request.
