How the numbers are computed

Finer droplets capture respirable dust far more effectively than coarse ones, but raising nozzle pressure gives diminishing returns as droplets approach the size where they can no longer shrink further. Meanwhile more airflow speeds up clearance but shortens the time dust spends in contact with the spray, so pushing airflow too high past the zone's design point erodes capture instead of helping it.

dropletFactor = 0.55 + 0.45·(1 − e^(−P/5))
efficiency η = clamp(35 + 0.16·Q + 0.032·L·dropletFactor
               − 0.10·max(0, Q−90), 0, 97) %
dust d = max(0.1, G·0.06·(1 − η/100))  mg/m³
water w = 4 + 0.016·L + 0.02·Q + 0.55·P  l/min

Q = air flow (m³/s), G = dust generation (%), L = spray-zone length (cm), P = nozzle pressure (bar). Each dust particle entering the spray zone rolls its own capture chance against η, so the animated capture rate fluctuates around the computed efficiency the way a real, noisy dust cloud would.
