A practical section covers scale-up rules and empirical corrections: maintaining constant tip speed vs. constant power per unit volume, and when each approach makes sense. The spreadsheet includes a compact table of common impellers with recommended Np, typical clearance ranges, and agitation intensity guidance — handy when you want to sanity-check a selection.
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. agitator design calculation xls repack
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. A practical section covers scale-up rules and empirical
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.

Structural and mechanical checks live in a separate sheet: shaft diameter from torsional and bending loads, bearing positions driven by overhung moments, and a safety-checked motor sizing that includes service factors and coupling losses. The repack computes torque envelopes across operating speeds and flags margins under different load cases (startup, steady-state, solids-laden).
