Fluid Phase Equilibria, Vol. 341, (2013), pp. 78-85
Note that there is a corrigendum to this paper in volume 348, p.83, 2013
The correlation is valid for temperatures in the range between 240 K to 412 K for pressures less than 6 MPa.
Enthalpy and entropy values are referenced to 200 kJ/kg and 1 kJ/kg-K, respectively, for saturated liquid at 0 C.
Liquid viscosity data are provided with the correlation from
