): Used to determine the flow regime (laminar, transition, or turbulent). Variables: Dacap D sub a (Impeller diameter), (Speed), (Density), (Viscosity). Power Requirement ( agitator design calculation xls repack

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. | Output | Method | |--------|--------| | Reynolds
