The most satisfactory law of variation of viscosity of a gas with temperature was proposed by W. Density relation with respect to temperature is given by F J McQuillan, J R Culham, MMYovanovichin their paper. McBride has also given the polynomial equation to solve specific heat, enthalpy and entropy which are dependent on temperature values. The values of coefficients to solve thermodynamic properties are taken from this paper. Abu-Mulaweh presented a study on isentropic compression of a gas with temperature-dependent specic heat capacities. This section provides a brief survey about the relevant literature and preliminary considerations of various thermodynamic properties of air. K = thermal conductivity in W/m-K = kinematic viscosity in m2/s KeywordsTemperature, air properties, specific heat, density, viscosity, thermal conductivity, diffusivityĬp= specific heat in kJ/kg-K T = temperature in K This computer code would be useful for the students in further detailed studies and hand calculations. At the end, details of a MATLAB computer program are presented. The reliance of these air properties with temperature is studied at atmospheric pressure. The main air properties presented in this paper are specific heat, density, dynamic viscosity, kinematic viscosity, thermal conductivity and thermal diffusivity.
