Ar

 

Ar provides ideal gas thermodynamic properties for argon valid over the temperature range from 100 K to 1500 K based on a constant pressure specific heat of 20.786 J/kmol-K. The reference state for specific enthalpy is 0 at 25 C.  The reference state for specific entropy is 154.837 at 298.15 K and 101.3 kPa

 

Transport property correlations were also taken from Yaws, Carl L., ed. Chemical Properties Handbook. New York: McGraw-Hill, 1999. 

 

The viscosity correlation is applicable for temperatures between 150 K and 1500  K.   

The thermal conductivity is applicable for temperatures between 150 K and 2000  K. 

 

Note that Ar provides thermodynamic properties assuming ideal gas behavior.  Use Argon to provide real fluid properties in the subcooled, saturated mixture, and superheated regimes.
