Reactor Sizing & Scale-Up Calculators Online

Reactor Sizing & Scale-Up Calculator

How to Use:

  1. Enter the physical properties of your fluid (density, viscosity) and the reactor geometry (impeller & tank diameter).
  2. Input the operating conditions, primarily the agitator speed.
  3. Select the type of impeller you are using. This will pre-fill typical constants (Np, Ks, Nt). You can override these with your own experimental or literature values.
  4. Click the "Calculate Parameters" button.
  5. All key scale-up parameters will be calculated and displayed simultaneously.
  6. Click "Show Details" for a full breakdown of the formulas, theory, and step-by-step calculations for all parameters.
Dimensionless. For turbulent flow (Re > 10,000).
For average shear rate. Dimensionless.
Also called N*t_m. Dimensionless.
