PROPS is an example FORTRAN program for directly accessing the Transport Subroutine Library. The interactive interface will prompt the user through a command-line interface for input to define the requested calculation, or the input can be provided by an input file, a sample of which is provided. The user can request calculation of temperature-dependent pure-species values of:
Isentropic speed of sound
Also, if a previously generated solution is available, the user can additionally request calculation of solution-dependent mixture values of:
Mixture viscosity
