If the Reynolds number is low, the flow is laminar (viscous forces dominate); if it is high, the flow is turbulent (inertial forces dominate). A standard spreadsheet calculates this automatically and then references a specific impeller chart for the next step.

Standard mixing tank configurations rely on established geometric proportions relative to the tank diameter ( Typically for axial flow impellers. Clearance ( ): Off-bottom distance of the impeller, usually Liquid Height ( If the Reynolds number is low, the flow
A modular, clean layout ensures that your design calculations are auditable and minimize user error. A standard industrial design file should feature the following tabs: Tab 1: Input Summary Project name, tag number, fluid name. Clearance ( ): Off-bottom distance of the impeller,
