WebAgitators are equipment that induces flow and shear to a fluid or material, which causes the fluid to homogenize. Mixers are used to blend two or more components rapidly. Agitators ensure homogeneity and equilibrium in an existing mixture. The main components of an agitator are the motor, shaft, and impeller. WebHistory. The concept of residence time originated in models of chemical reactors. The first such model was an axial dispersion model by Irving Langmuir in 1908. This received little attention for 45 years; other models were developed such as the plug flow reactor model and the continuous stirred-tank reactor, and the concept of a washout function …
