PROPYLENE provides high accuracy thermodynamic and transport properties for propylene (C3H6, R1270, Molar mass = 42.080 g/mole) using the Fundamental Equation of State presented by Reiner Tillner-Roth, "Fundamental Equations of State", Shaker, Verlag, Aachan, 1998. This equation of state is valid for temperatures between 100 K < T < 600 K and for pressures up to 200 MPa. The source of the data for this formulation is:
Angus, S., Armstrong, B. and de Reuck, K.M., International Thermodynamic Tables of the Fluid State-7 Propylene, International Union of Pure and Applied Chemistry, Pergamon Press, Oxford, 1980.
Ancillary equations for vapor pressure and saturated liquid and vapor density are provided by Professor Steve Penoncello, College of Engineering, University of Idaho, Moscow, Idaho, 83844-1011
T=298.15 K, P=101.325 kPa: h=0 kJ/kg, s=0 kJ/kg-K in ideal gas state. The reference state can be changed using the $Reference directive.
Transport and surface tension data were fit from the tabular data provided by:
P.E. Liley and P.D. Desai,
"Thermophysical Properties of Refrigerants", ASHRAE, 1993, ISBN 1-1883413-10-9.
The valid temperature ranges for these transport data are as follows:
gas phase viscosity: 225 K < T < 575 K
liquid phase viscosity: 100 K < T < 325 K
gas phase thermal conductivity: 200 K < T < 600 K
liquid phase thermal conductivity: 100 K < T < 360 K
Surface tension data are provided using the information in:
