Mechanical Agitator Power Requirements for Liquid Batches

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

This two hour course will focus on deriving the general Application Equation used for calculating the mechanical agitator power requirements for liquid batches. The power requirement is based on a relationship of the agitator type, agitator speed, and liquid physical properties. Following the Application Equation derivation, correlations are presented from the open literature which define the methodology for calculating the power requirements for various agitator types. An industrial example is given in order to demonstrate the calculation techniques for determining specific power requirements. The example calculates the power required to mix water in a vessel with a flat blade turbine at an agitator speed of 60 rpm. This course includes a True-False quiz at the end, which is designed to enhance the understanding of the course materials.
