Heating and Cooling of Agitated Liquid Batches: Isothermal Medium

John Frank Pietranski, P.E., Ph.D.

This course provides the student with application equations that allow for calculating the transient time required for heating and cooling of liquid batches from an initial temperature to a final temperature. The course will derive the application equations from a differential heat balance. Several simplifying assumptions are utilized which result in an exact solution of the integrated form of the differential heat balance equation. Following the derivation of the application equations, two industrial examples will be given. The first is a steam supplied jacketed vessel used to heat an agitated batch of cold water, and, the second, a refrigerant submerged coil in a tank used to cool an agitated batch of hot water. This course includes a True-False quiz at the end.
