PROPANE_mh provides thermodynamic properties of C3H8 using the Martin-Hou equation of state (A.I.Ch.E. Journal, 1:142, 1955).
The Martin-Hou equation of state is valid for states in which the density is less than 1.5 times the critical density. Properties in the vicinity of the critical point and at high pressures may be inaccurate. Properties in the subcooled region are determined by assuming the fluid is incompressible. Use fluid PROPANE for more accurate property data.
Note that PROPANE_mh provides thermodynamic properties assuming real fluid behavior. The reference state for specific enthalpy and entropy is 0 for saturated liquid at 233.16 K. Use C3H8 for ideal gas properties of propane consistent with reference states used in combustion calculations.
Range of applicability for transport function correlations:
Gas-phase viscosity: 240 K to 530 K
Liquid-phase viscosity: 210 K to 370 K
Gas-phase thermal conductivity: 240 K to 530 K
Liquid-phase thermal conductivity: 210 K to 370 K
Surface tension data were fit to data obtained from the NIST REFPROP 6 program (M.O. McLinden, S.A. Klein, E.W. Lemmon and A.P. Peskin, Physical and Chemical Properties Division, National Institute of Standards and Technology, Boulder, CO 80303, 1995. The range of applicability of the data are from 86 K to the 369.8 K.
