MODEL & BOUNDARIES
Know what the result means.
Actual fans, nonuniform flow, fouling and bypass need measurement. This is a conservation/pressure-work calculation, not a capture prediction. Electrical collection power is additional.
Version 1.0 · SI quantities are used internally, with displayed input units converted explicitly. Retain your assumptions with any exported result.
