Mixing rates in agitated vessels are predicted through measurement of the flow patterns which determine them. These measurements suggest the use of a model that assumes that nearly all the mixing occurs in a small "perfectly mixed" region near the impeller, with flow throughout the remainder of the tank serving primarily to bring the fluid into this region of the impeller.
