Calculate power needed for mixing systems
Scale mixing parameters from lab to production
The power required by an agitator is calculated using the power number (Nₚ):
P = Nₚ × ρ × N³ × D⁵
Where:
P = power (W)
Nₚ = power number
ρ = density (kg/m³)
N = rotational speed (rev/s)
D = impeller diameter (m)
Different scale-up methods prioritize different mixing aspects:
Scale Factor = (V₂ / V₁)¹/³
Where:
V₁ = lab volume
V₂ = production volume
Methods include constant power/volume, tip speed, Reynolds number, or mixing time.
