A standard agitator design spreadsheet is not a monolithic black box. Instead, it is organized into logical modules, typically including the following key sections:

The power number is a dimensionless quantity that depends on the impeller type and NRecap N sub cap R e end-sub . The spreadsheet should feature a lookup table for Npcap N sub p based on the selected impeller. C. Power Calculation (P) The power required (in Watts) is calculated as: Can’t copy the link right now

Beyond power, mixing quality depends on flow rate. The spreadsheet calculates: Q = Nq * N * D^3 (where Nq = pumping number, ~0.7 for axial impellers, ~0.3 for radial).
Designing agitators involves complex iterative calculations. A well-constructed XLS file allows engineers to:
