C3H8
C3H8 provides ideal gas thermodynamic properties for propane valid over the temperature range from 200 K to 6000 K based on the property information provided by McBride (2002). The reference state for specific enthalpy is based on the enthalpy of formation relative to the elements at 25 C. The reference state for specific entropy is based on the Third Law of Thermodynamics. The reference values are from:

The viscosity correlation is valid for temperatures between 85 K and 650 K.

The thermal conductivity correlation is applicable for temperatures between 200K and 600 K.
Note that C3H8 provides thermodynamic properties assuming ideal gas behavior. Use PROPANE or R290 to provide real fluid properties in the subcooled, saturated mixture, and superheated regimes.
