VISCOSITIES OF SOLUTIONS AND MIXTURES

Abstract

In industrial practice, viscosities of solutions (meaning homogeneous products of dissolution of solids or gases in liquids) and fluid mixtures (meaning homogeneous mixtures resulting out of mixing of two or more fluids) are often needed for the design of the different unit operations and processes involved. While it will be ideal to measure the viscosities of the solutions and mixtures at the conditions of interest, constraints on the availability of time, facilities and expertise, often force the designer to use an estimated value. The objective of this chapter is to outline the methods available in the literature for the estimation of the viscosity of solutions and mixtures.
