The Effect of Co-Saturated Salts on the Kinematic Viscosity of Water

Abstract

It is well documented in the literature how individual salts such as sodium chloride (NaCl) and potassium chloride (KCl) effect the kinematic viscosity of a water solution. However, there exists little to no information on how the presence of both NaCl and KCl in a co-saturated state affect the kinematic viscosity of the solution. This paper reviews experimental measurements of co-saturated aqueous NaCl:KCl solutions across the temperature range of 20-65 oC at three different concentration ratios. These data are compared to the known kinematic viscosity curves of saturated NaCl solution and pure water from literature.
