Stirred tank reactor yields are successfully described by the following model. The impeller is considered to act as a local micro‐mixer that perfectly mixes the recirculating stream down to the molecular level. All other portions of the vessel act as a large volume macro‐mixer, throughout which the impeller discharge stream remains completely segregated. Changes in overall conversion due to variations in mean residence time, impeller size, and rev./min. as predicted by this micro‐ and macro‐mixer model agree with Worrell's data for a relatively slow, second‐order, irreversible reaction.
