ISOPENTANE
ISOPENTANE provides high accuracy thermodynamic properties for isopentane (Molar mass =72.115 g/mole) using the Fundamental Equation of State, as described by Reiner Tillner-Roth, "Fundamental Equations of State", Shaker, Verlag, Aachan, 1998. The correlation is based on data from:
Polt, A., Platzer, B., and Maurer, G.
"Parameter der thermischen Zustandsgleichung von Bender fuer 14 mehratomige reine Stoffe,"
Chem. Tech. (Leipzig), Volume 44, Number 6, pp. 216-224, 1992.
The parameters for the fundamental equation of state were provided by Professor Steve Penoncello, College of Engineering, University of Idaho, Moscow, Idaho, 83844-1011
Reference State
h = 0 kJ/kg, s = 0 kJ/kg-K at 298.15 K, 1 kPa. The reference state can be changed using the $Reference directive.
Range of applicability for equation of state:
273 K < T < 553 K
0 < P < 7.5 MPa
