High-viscosity impellers that sweep the tank wall to prevent local overheating or dead zones. Geometric Ratios Calculated based on maximum torque and allowable shear
What (e.g., hydrofoil, Rushton turbine, anchor) are you using? What is the viscosity range of your fluid? viscous forces dominate
For , viscous forces dominate, and the formula adjusts to:
