For solids handling, the workbook steps through suspension criteria using just a few measured or estimated inputs: particle size, density difference, and desired mixing degree. A dedicated table shows multiple impeller options (marine, pitched-blade, turbine), their expected flow patterns, and calculated minimum tip speed to keep particles suspended. A quick “what-if” area lets you instantly compare impeller sizes and speeds — the kind of instant feedback that turns design iteration into experimentation.
Documentation and traceability are built-in: each calculation block has a brief note citing the correlation source and applicability notes (e.g., "valid for Re > 10,000" or "empirical for non-cohesive solids"). A printable summary sheet aggregates final specs — impeller type and size, speed, motor power, shaft diameter, and expected power draw — ready for procurement or review. agitator design calculation xls repack
Next comes the core: hydrodynamic sizing. The repack lays out familiar correlations—power number (Np) tied to impeller type, Reynolds number to determine flow regime, and impeller diameter as a fraction of tank diameter. Behind the scenes, formulas dynamically switch between laminar and turbulent regimes, swapping in the correct Np and flow coefficient. Conditional formatting highlights when an assumed regime changes, nudging you to review assumptions. For solids handling, the workbook steps through suspension
Imagine an Excel workbook reborn: a compact, polished "repack" of agitator design calculations that turns messy engineering theory into a sleek, usable tool. This repack is less about bulky manuals and more about a living spreadsheet that guides you from process need to final shaft torque with clarity and a little engineering flair. it scaffolds it.
A good repack doesn’t hide complexity; it scaffolds it. The workbook folds advanced options into collapsed sections: multi-impeller arrangements, baffle effects, and CFD cross-check placeholders (with steps to export key geometries). For curious users, there’s a mini-tutorial sheet that walks through a sample calculation, showing how each input propagates to the output.
