Dissolving solids in liquid: similar to mixing miscible liquids, the pumping action helps dissolving and keeping the ingredients in solution. In-line mixing. According to him, (i) convective mixing refers to the transfer of groups of adjacent particles from one location in the mass to another, (ii) diffusive mixing is the distribution of particles over a freshly developed surface, and (HI) shear mixing takes place when slipping planes within the mass occur. The definition of viscosity is the ratio of shear stress to shear rate. Any real fluids (liquids and gases included) moving along solid boundary will incur a shear stress on that boundary.
