Before finalizing any output from your agitator design XLS, verify that your parameters meet these typical industrial baselines: Recommended Design Limit / Check Ideal range is for single impellers. D/T Ratio for turbulent systems; >0.6is greater than 0.6 for high viscosity. Tip Speed Low shear: 5is greater than 5 Operating Speed of the calculated first critical speed. Motor Margin

This updated version (v3.2) includes:

The most critical calculation for motor sizing. $$ P_\textshaft = N_p \times \rho \times N^3 \times D^5 $$ (Ensure units are consistent; typically Watts).

Determines if the flow is laminar or turbulent. $$ N_Re = \fracD^2 \times N \times \rho\mu $$

The motor must overcome mechanical losses from the gearbox and shaft seals.
