📐 Impeller Scaling Optimizer

Predict new fan performance (Q, P, W) by scaling the impeller diameter (D) while keeping the fan speed (N) constant.

1. Initial Fan Performance (D₁)

Initial Airflow (Q₁)

Initial Static Pressure (P₁)

Initial Input Power (W₁)

Initial Impeller Diameter (D₁)

2. Target Diameter & Constant Speed

Target Impeller Diameter (D₂)

Constant Fan Speed (N) (N must be constant for these laws to apply.)

Note on Diameter Scaling Laws: These scaling laws assume that the fan geometry remains strictly similar (maintaining constant efficiency). Small changes in D can generally be predicted accurately. For large scaling factors or non-similar geometries, the actual performance may vary.
