<<Agitator-equipped vessels with jackets for heating or cooling are drawing increased attention in the process industries. Apart from a growing importance in biotechnology (box, p. 94), such vessels are widely used in a variety of other process applications. Accordingly, engineers can benefit from a working knowledge of how heat-transfer and temperature-control principles apply to such vessels. The rate of heat transfer to or from an agitated liquid mass in a vessel is a function of the physical properties of that liquid and of the heating or cooling medium, the vessel geometry, and the degree of agitation. The type, and size of the agitator, as well as its location in the vessel, also affect the rate.>>
