Water properties - Kestin model for viscosity

The model from Kestin et al. can be selected for the computation of brine viscosity, valid for a pressure, temperature and salt concentration range of \(0.1 < P < 35\) MPa, \(20 < T < 150\) °C and \(0 < C < 5.4\) Molal. The model guarantees an accuracy of 0.5% with experimental data. For more details, please refer to [KKC81].

See example below:

EOS WATER
  SURFACE_DENSITY 1004.0 kg/m^3
  VISCOSITY KESTIN
END

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