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.
