is relatively constant, but it changes drastically in the laminar or transition region. C. Power Requirement ( The total power required to drive the agitator:
Elena, a lead process engineer at a specialty chemical plant, was facing a disaster. A new polymer batch was coming out "streaky"—unblended and unusable. The old agitator was struggling with the rising viscosity, and the motor was running hot. She needed a new design, and she needed it fast. The Hero: The Design Spreadsheet agitator design calculation xls
The volumetric flow rate (pumping capacity) generated by the impeller is calculated using the pumping number (Nq).
): A dimensionless constant specific to the impeller geometry (e.g., Marine propeller, Rushton turbine, Hydrofoil) under fully turbulent conditions. 3. Step-by-Step Agitator Design Calculations
), which is a constant unique to each impeller type in the turbulent regime: If you'd like to build or refine your
Define the required pumping rate or "intensity" of agitation (e.g., mild, medium, or violent). 2. Impeller & Speed Selection
Directly link calculated power to standard motor sizing tables. 2. Key Input Parameters for Agitator Design
Account for transmission losses (gearbox efficiency) and a safety factor (typically 1.15 to 1.25) to select the motor capacity. 4. Mechanical Design & Safety Power Requirement ( The total power required to
