Agitator Design Calculation Xls May 2026

The design and calculation of an industrial agitator (or mixer) involves determining the mechanical and process parameters required to achieve a specific mixing duty. For a spreadsheet-based approach (XLS), the fundamental goal is to calculate the motor power (HP/kW), shaft diameter, and critical speed based on fluid properties and vessel geometry. 1.

. This metric allows engineers to scale a 10-liter lab experiment up to a 10,000-liter industrial vat. A well-built XLS sheet will flag if the energy consumption is too high, prompting a change in impeller diameter or RPM to save on long-term electricity costs. agitator design calculation xls

The spreadsheet then adds mechanical losses (typically 10-20%) and safety factors: Motor Power (kW) = (P * Safety Factor) / (Drive Efficiency) The design and calculation of an industrial agitator

• Torsional stress from motor torque.
• Critical speed: The spreadsheet calculates the natural frequency of the shaft. A simple vibration check flags if the operating speed (N) is within 15% of the calculated critical speed—a dangerous condition to avoid.

Shaft design checks:

The spreadsheet should automatically compute the following values based on your inputs: Reynolds Number ( NRecap N sub cap R e end-sub ): is the rotational speed in revolutions per second (RPS). Power Requirement ( ): Torsional stress from motor torque
