Engineering Tools
Do the first pass yourself. We review the project-specific pass.
These tools are based on commonly used first-pass correlations and specification geometry. Free, no signup — calculations run entirely in your browser, your inputs never leave your device.
Souders-Brown sizing
Vmax = K · √((ρL − ρV) / ρV)
Estimated Vmax → preliminary required pad flow area
Mesh / micron conversion
aperture (µm) = 25,400 / mesh count − wire Ø (µm)
Mesh count = openings per inch; square-weave cloth only
Demister Sizing Calculator (Souders-Brown) →
Enter gas flow and phase densities — get maximum allowable vapor velocity, required pad cross-section and equivalent round flow diameter.
Spec conversionMesh / Micron / Wire Gauge Converter →
Convert between mesh count, aperture in microns and SWG wire gauge; instantly check open area for square-weave cloth.
From Calculation to Specification
