Viscosity plays an important role in quantifying heat and mass transfer rates as depicted in theoretical and semi-empirical correlations. In practical problems where extreme temperatures and solute concentrations are encountered, viscosity data is usually unavailable. At these conditions, no dependable correlation appears to exist in the literature. This paper uses the hole type model to predict the viscosity of aqueous electrolytes containing single and mixed salts up to the molten salt regime. This model needs two parameters which can be evaluated from sparse data. For LiBr/water and (Li, K, na) NO[sub 3]/water mixtures, it is shown that the agreement between predicted and experimental values is very good over wide temperature and concentration ranges. The deviation between these two values was found to be less than 9%.
