This tool uses industry-standard engineering equations. Pressure drop is calculated via the Hesketh equation (EPA APTI-413 reference), collection efficiency via the Johnstone equation (η = 1 − e−k·R·√ψ), and droplet size via the Nukiyama-Tanasawa correlation.
What is Liquid-to-Gas (L/G) Ratio? The volume of scrubbing liquid injected per unit volume of gas. Too low = insufficient contact area; too high = unnecessary energy consumption. Optimal range: 0.5–2.5 L/m³.
Impaction Parameter (ψ) is a dimensionless Stokes number expressing the probability of a particle colliding with a liquid droplet due to inertia. It scales with the square of particle diameter, which is why efficiency drops dramatically for fine particles (< 1 µm).
