  • Droplet interception and Brownian diffusion (for fine particles) — include diffusion efficiency approx:
    1. Replace static equations with: 
      =IF(throat_velocity > 150, "Warning: high velocity", pressure_drop_calc)
    2. Add NIST steam table lookup for saturation temperature.
    3. Include particle penetration for 0.1–10 µm (use log-normal distribution).
    4. Add design margin (10–20% on gas flow).
    5. Link throat ΔP to fan power – P_fan = (Q_g * ΔP) / fan_eff.
