C5H12

 

C5H12 provides ideal gas thermodynamic properties for n-pentane valid over the temperature range from 200 K to 1500 K based on the constant pressure specific heat correlation from Yaws, Carl L., ed. Chemical Properties Handbook. New York: McGraw-Hill, 1999. 

 

The reference state for specific enthalpy is based on the enthalpy of formation relative to the elements (-146,440 kJ/kmol)  at 25 C.  The reference state for specific entropy is determined by the Third Law of Thermodynamics.

 

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 300 K and 900  K.   

The thermal conductivity is applicable for temperatures between 225 K and 480  K. 

 

Note that C5H12 provides thermodynamic properties assuming ideal gas behavior.  Use n-pentane or isopentane to provide real fluid properties in the subcooled, saturated mixture, and superheated regimes of these fluids
