The design and calculation of an agitator involve determining the power required to move a fluid and ensuring the mechanical integrity of the shaft. Standard verified methods rely on fluid properties, vessel geometry, and dimensionless numbers such as the Reynolds number ( cap N sub cap R e end-sub ) and Power number ( cap N sub p 1. Identify Fluid and Vessel Parameters Begin by collecting essential data for the application: Fluid Properties: ) and Viscosity ( Vessel Geometry: Tank diameter ( ) and liquid height ( ). A typical ratio is between Impeller Details: Type (e.g., Marine Propeller Rushton Turbine ), diameter ( cap D sub a ), and rotational speed ( ) in revolutions per second. Verito Engineering Private Limited 2. Determine the Flow Regime Calculate the impeller Reynolds number to determine if the flow is laminar ( ), transitional, or turbulent (
Includes losses from the gearbox and seals (typically 10-20% additional). 2. Mechanical Shaft Design agitator design calculation pdf download verified
