**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
