Thermodynamic and Thermophysical Properties of Air as a Mixture by Using Schreiber-Pitzer EoS

Air is one of the most important substances used in industrial and technological applications. Applications air require a consistent set reliable data on its thermodynamic thermophysical properties. Over last few decades, researchers have developed number empirical theoretical models for correlation prediction properties pure fluids mixtures. The ideal gas Equation State (EoS) property calculations extensively, but applications with higher pressure zones, error levels are increasing. For applications, an equation state better accuracy will be required extreme cases. In this study, Schreiber-Pitzer EoS considered mixture. A computer programs were java language to calculate as mixture Nitrogen, Oxygen Argon. results compared Peng-Robinson EoS, Redlich-Kwong Van der Waals utilizing cubic spline curve fitting cp values. percentages differences calculated. increasing decreasing temperature.
