This technical guide outlines the critical parameters and formulas for developing an agitator design calculation spreadsheet (XLS). Whether you are building a tool from scratch or "repacking" a legacy template for modern industrial standards, these calculations ensure mechanical integrity and process efficiency. 1. Core Process Parameters
Safety Factors: Include a 1.1x to 1.5x service factor for fluctuating loads or high-viscosity "slugs." Summary Table for XLS Headers Formula/Source Impeller Speed User Input Power Number Npcap N sub p Table Lookup Absorbed Power Total Torque Tqcap T sub q Shaft Stress Combined Torsion/Bending
Performing agitator design calculations using XLS repack involves the following steps:
The repack outputs a one-page dashboard containing:
Using an Agitator Design Spreadsheet, engineers can input specific parameters to generate precise outputs. 1. Input Parameters
Torque & Bending: Calculations account for torque during startup and bending moments caused by hydraulic forces on the blades. Critical Speed ( Nccap N sub c
