C4H10 provides ideal gas thermodynamic properties for n-butane valid over the temperature range from 200 K to 3500 K based on property information from McBride et al.(2002).  The reference state for specific enthalpy is based on the enthalpy of formation relative to the elements at 25C.  The reference state for specific entropy is based on the Third Law of Thermodynamics.  The reference values are from:

Transport property correlations were developed from data provided in:


Thermophysical Properties of Matter

Vol. 3:  Thermal Conductivity, Y.S. Touloukian, P.E. Liley, S.C. Saxena

Vol. 11: Viscosity,  Y.S. Touloukian, S.C. Saxena, and P. Hestermans

IFI/Plenun, NY, 1970, ISBN 0-306067020-8   


The viscosity and thermal conductivity correlations are applicable for temperatures between 270 K and 520  K.   


Note that C4H10 provides thermodynamic properties assuming ideal gas behavior.  Use n-Butane or isobutane to provide real fluid properties in the subcooled, saturated mixture, and superheated regimes.
