Summary
<p>Dry air is widely used in industrial and technological applications. Ideal gas EoS is used in dry air thermodynamic</p><p>property calculations. For most applications, it might be sufficient, but when applications with higher pressure zones</p><p>are considered, error level will increase. Peng-Robinson cubic Eq. of states is considered for better accuracy of the</p><p>thermodynamic properties for dry air in this paper. So, the objective of this study is to suggest a more accurate EoS</p><p>for thermodynamic and heat transfer analyses. Set of computer programs were developed in java language to calculate</p><p>thermodynamic properties like specific volume, internal energy, enthalpy, entropy, Gibbs energy, Helmholtz energy,</p><p>specific heat, thermal conductivity, and viscosity of dry air. The results are compared with the perfect gas EoS and</p><p>the Eq.s developed by The International Association for the Properties of Water and Steam (IAPWS).</p>
