This program was written to be used as a subroutine. The program determines the thermodynamics of light hydrocarbons. The following light hydrocarbons can be analyzed: butane, ethane, ethylene, heptane, hexane, isobutane, isopentane, methane, octane, pentane, propane and propylene. The subroutine can evaluate a thermodynamic state for the light hydrocarbons given any of the following pairs of state quantities: pressure and quality, pressure and enthalpy, pressure and entropy, temperature and pressure, temperature and quality and temperature and specific volume. These six pairs of knowns allow the user to analyze any thermodynamic cycle utilizing a light hydrocarbon as the working fluid. The Starling--Benedict--Webb--Rubin equation of state was used. A brief description, flowchart, listing and required equations for each subroutine are included.
