This guide breaks down the core calculations, scaling parameters, and structural components embedded within a professional-grade mixing calculation sheet. 1. Core Objectives of Agitation Engineering
Beyond drawing power, an agitator must achieve specific process results: blending, solids suspension, gas dispersion, or heat transfer. Pumping Rate and Turnover The volume of fluid pumped by the impeller per unit time ( ) is determined by the Flow Number ( Nqcap N sub q
These calculations ensure the agitator performs its intended mixing function (e.g., blending, solid suspension, heat transfer).
The repack outputs a one-page dashboard containing: agitator design calculation xls repack
The engineer begins by entering the tank's diameter, cylindrical height, liquid level, and total volume.
: Calculation of the Impeller-to-Tank diameter ratio (
The repack should offer at least six impeller types: This guide breaks down the core calculations, scaling
But for now, nothing beats a clean, well-organized running on your local machine.

What are the ? (specifically viscosity and density) Are you working with a specific impeller type ? Pumping Rate and Turnover The volume of fluid
If the Reynolds number is low, the flow is laminar (viscous forces dominate); if it is high, the flow is turbulent (inertial forces dominate). A standard spreadsheet calculates this automatically and then references a specific impeller chart for the next step.
