Jones-Dole Electrolyte Correction
The Jones-Dole model calculates the correction to the liquid mixture viscosity
of a solvent mixture, due to the presence of electrolytes:
Where:
�solv = Viscosity of the liquid solvent mixture, by default
calculated by the Andrade model
��ca l = Contribution to the viscosity correction due to
apparent electrolyte ca
The parameter �solv can be calculated by different models depending on
option code 3 for MUL2JONS:
Option Code Solvent liquid mixture viscosity
Value
model
0
Andrade liquid mixture viscosity
model (default)
1 Viscosity quadratic mixing rule
2 Aspen liquid mixture viscosity
model
The parameter ��ca l can be calculated by three different equations.

† When the concentration of apparent electrolyte exceeds 0.1 M, the Breslau-
Miller equation is used instead.
