Mixing is the movement of fluids and solids to enhance a process result, which is accomplished by means of an agitation source. The process of mixing is concerned with all combinations of phases, of which the most frequently occurring include gases with gases, gases into liquids, and gases with granular solids.

Liquid mixing can be a fairly straight forward process when the liquids are of similar or equal viscosity and the liquids are miscible. In these instances conventional mixing equipment such as stirrers and in-tank agitators will produce satisfactory results. The liquid - liquid mixing process gets more complex when immiscible liquids are to …

The influence of agitator speed in a vessel with a fixed liquid volume is seen from the first column, which confirms the generality that higher speed results in faster mixing. For top-entering agitators, the "mixing time" varies roughly as the inverse first power of the speed.
