Water properties - Batzle and Wang model¶
The model from Batzle and Wang (1992) is also available for the computation of water density and viscosity, valid for a pressure and temperature range of \(5 < P < 100\) MPa, and \(20 < T < 350\) °C. This model is considered one of the most accurate for high level of salinity, up to 320000 mg/L. For more details, please refer to [BW92].
See example below:

Note that in the BATZLE_AND_WANG example described above, the IFC67 default model is used for enthalpy, because no other model is specified.
