1 1.0 ABSTRACT Mixing is a common operation in the process industries and is generally performed by a rotating impeller in a vessel. Products obtained from foo, petroleum, mining, pharmaceutical, pulp and paper, and chemical industries would not be available without fluid mixing equipment and technology. Mixing also plays a vital role in industry waste treatment and in environmental cleaning such as in sulfur dioxide absorption for treatment of acid rain. A high range of mixing situation can be found in practice which may involved high or low viscosity fluids, suspending solid in liquids. Mixing operations at the industrial level are increasingly carried out a low to mo derate Reynolds numbers, leading to segregated o r dead regions and resulting in long mixtures times, the simplest way use to improve mixing efficiency consist of increasing the rotational speed, which unfortunately leads to higher energy consumption. Mixing times in small scale stirred tank are commonly measu red by non intrusive techniques such as colorimetry. This technique also allows observation of aforementioned segregated regions and how they tend to disappear as the impellar speed increase. The purpose of this experiment consists of determining the mixing time with two impellers providing different flow patterns. The mixing time, defined as the time needed to reach a specified degree of homogeneity can be determined by various technique.
