The correlation is valid for temperatures in the range between 165 K and 500 K for pressures less than 50 MPa. Enthalpy and entropy values are referenced to 200 kJ/kg and 1.0 kJ/kg-K, respectively, for saturated liquid at 0°C.
Transport properties for the liquid are provided using correlations based on data provided by 3M Corporation in:
Note that an older, less accurate formulation for Novec649 properties was provided with fluid name C6_Fluoroketone. This fluid remains in the database for backward compatibility, but it should no longer be used.
