Necessary for selecting the drive unit (gearbox) and shaft sizing.

To build or use an effective agitator design tool, the following sections are essential for accuracy and industrial safety: 1. Input Parameters (Fluid & Vessel Geometry) agitator design calculation xls

A professionally developed spreadsheet can greatly accelerate design. Here are some sources:

) is the power delivered to the fluid (shaft power). To size the actual motor, you must account for mechanical losses in the gearbox and seals.

This article explores the fundamental components required to create or use an effective agitator design Excel spreadsheet to ensure optimal mixing performance. 1. Why Use an Excel Spreadsheet for Agitator Design? NRe=ρ⋅N⋅D2μcap N sub cap R e end-sub equals

= Power_No * Density * (RPS^3) * (Impeller_Dia^5) Cell Engine 3 (Torque): = Absorbed_Power / (2 * PI() * RPS)

tables, calculates shaft power, and outputs recommended motor HP. VLOOKUP or XLOOKUP for Npcap N sub p

The spreadsheet will request the physical dimensions of the vessel. Common inputs include: Here are some sources: ) is the power

For an optimized design, your spreadsheet should cross-reference calculations against industry standard ratios: Parameter Ratio Standard Range 0.3 to 0.45 Optimizes flow vs. power shear Liquid Height / Tank Diameter ( ) 1.0 to 1.2 Ensures equal top-to-bottom blending Baffle Width / Tank Diameter ( ) 0.083 (1/12th) Prevents vortexing and swirling Impeller Clearance / Tank Diameter ( ) 0.33 (1/3rd) Maximizes off-bottom fluid lifting 5. Common Design Pitfalls to Avoid in Excel

Always divide the calculated absorbed power by the mechanical efficiency of the gearbox (typically 85-95%) and motor to determine the required nameplate motor power. Static Power Numbers: Npcap N sub p is only constant in fully turbulent regimes (

He punched in the density and viscosity.
