Agitator Design Calculation Xls · Trusted Source
With the XLS data in hand, Elena ordered a new gear-driven agitator with a 5 kW motor, specifically sized using the motor selection guidelines from her calculations.
If the Reynolds number indicates turbulent flow and no baffles are selected, flag a warning in the XLS to add baffles. Critical Speed: Ensure the operational speed ( ) does not fall within

The Reynolds number determines the flow regime inside the mixing vessel.
Hydraulic forces acting on the impeller blades create a bending moment on the shaft, especially during liquid level transitions. M=Fh⋅Lcap M equals cap F sub h center dot cap L Fhcap F sub h is the hydraulic force and is the shaft overhang length from the lowest bearing. Minimum Shaft Diameter ( With the XLS data in hand, Elena ordered
From calculating the Reynolds number and power requirement to determining shaft torque and mixing intensity, a well‑designed Excel file empowers engineers to design efficient, reliable, and cost‑effective agitation systems. Whether you download a pre‑built spreadsheet from Cheresources or build your own, mastering this tool is a critical step toward excellence in process equipment design.
Before initiating geometric or mechanical calculations, you must define the physical properties of the fluid and the process objectives. These inputs dictate the mixing regime and power requirements. Key Inputs Required for the XLS Mass per unit volume ( kg/m3kg/m cubed Dynamic Viscosity ( ): Fluid resistance to shear ( Tank Diameter ( ): Internal diameter of the mixing vessel ( Liquid Height ( ): Level of the liquid inside the tank ( Agitator Speed ( Hydraulic forces acting on the impeller blades create

Using a structured Excel template offers several advantages:
) and Torque : She began swapping impeller types in the dropdown menu. A standard pitched blade wouldn't cut it. She selected a high-viscosity hydrofoil. The XLS updated the from ResearchGate , calculating the exact motor power required to keep the blades turning without burning out the motor.
