The power required by an agitator is calculated using the power number (Nₚ):
Where P is power (W), Nₚ is power number, ρ is density (kg/m³), N is rotational speed (rev/s), and D is impeller diameter (m).
Different scale-up methods prioritize different mixing aspects:
Where V₁ is lab volume and V₂ is production volume. Methods include constant power/volume, tip speed, Reynolds number, or mixing time.
