AIRFLOW, WITH THE MATH LEFT VISIBLE

Find where your fan meets your duct.

Give DustRoute a real fan curve and one-open-gate duct routes. It finds each operating point, shows where pressure goes, and fails the constraints you wrote down.

OPERATING POINT Fan pressure = route loss
Fan and system curve intersection A falling fan curve crosses a rising system-loss curve at the calculated operating point. fan system work here airflow pressure
01 Piecewise fan interpolation + Darcy–Weisbach route loss

WHAT IT DOES

A compact solver, not a rule-of-thumb calculator.

  1. 01Interpolate your supplied fan curve.
  2. 02Calculate wall and fitting losses per segment.
  3. 03Bisect the fan/system intersection.
  4. 04Compare CFM and velocity to your constraints.
