Choose a tool for mesh dimensions, weight, open area, flow or measured filter data. Each page explains what to enter, how to interpret the result and which conditions to check before using it in a specification.
Convert mesh count and wire diameter into aperture, micron size, pitch and theoretical open area.
Search 39 historical Filtalloy catalog entries across plain, twilled and reverse Dutch weave. Compare warp/weft mesh counts and wire diameters; catalog reference apertures are not certified micron filtration ratings.
Open Dutch Weave LookupLook up selected test-sieve nominal apertures and compare nearby historical Tyler and U.S. sieve reference values. Approximate sizes are not standards equivalence or filtration ratings.
Open Sieve LookupEstimate cylindrical blank dimensions from a verified development diameter or an explicit mid-wall approximation.
Calculate gross roll area, required roll length or rectangular cut-piece quantities with trims and spacing.
Compare circular disc counts and yield for straight and staggered cutting layouts.
Open CalculatorEstimate solid or perforated sheet weight from material, dimensions, thickness, quantity and open area.
Estimate single-layer woven mesh weight, or sum confirmed unit-area masses for multi-layer mesh parts.
Calculate round, square, rectangular and perforated metal tube weight from section dimensions and material density.
Estimate the solid-metal weight of a finished circular disc or annular ring from diameter, centre opening, thickness and material density.
Calculate solid round wire net mass, mass per metre or length from net mass and actual material density.
Scale measured coating mass gain to comparable projected mesh area.
Open CalculatorCalculate the theoretical open area of common perforation patterns using hole size and pitch.
Estimate complete round-hole counts on a finished rectangular sheet with blank edge margins and centre pitch.
Estimate clear opening area and finished-tube open area after unperforated ends and a longitudinal weld strip.
Estimate opening area after blank margins and blocked zones, or find hole size and pitch for a target whole-sheet open percentage.
Calculate shaped mesh bulk density, theoretical porosity or required net mass from project-specific dimensions and solid material density.
Estimate Johnson screen local and overall open area, or reverse-calculate slot width.
Estimate theoretical total porosity, target net mass or thickness from measured dimensions and alloy density.
Estimate Souders–Brown gas velocity and net exposed area using a project-justified K factor. Does not predict droplet removal efficiency or pressure drop.
Open Demister EstimatorEstimate cylinder or pleated filter area, then calculate filter face velocity or required active area from operating flow.
Convert flow, calculate velocity and estimate pressure drop with separate models for pipe, screen loss and porous filter media.
Convert standard or normal gas flow to actual volumetric flow using entered reference and operating conditions.
Calculate mean pipe velocity, actual volume flow and Reynolds number from inside diameter and fluid viscosity.
Estimate clean sintered mesh media pressure drop using measured permeability or scale a reference test for the same element.
Calculate average opening velocity or actual volumetric flow using net geometric open area.
Back-calculate apparent directional permeability from measured liquid flow and media-only pressure drop.
Add the linear Darcy resistance of planar liquid-filter layers sharing the same gross flow area.
Interpolate flow and pressure drop between measured points without extrapolation.
Open CalculatorReview material-specific corrosion concerns for seven metal families and seven chemical environments. Identifies required checks without declaring a material approved for service.
Open Material Review ToolConvert beta ratio and apparent particle removal efficiency at a specified size.
Open CalculatorCompare measured pressure drops before and after cleaning under matching conditions.
Open CalculatorScale measured holding capacity by effective area under comparable test conditions.
Open CalculatorEstimate equivalent pore size or bubble-test pressure for fully wetted sintered metal media, with a liquid-head correction. Not a filtration rating.
Open CalculatorCompare direct replacement and cleaning costs, cost per treated volume and arithmetic break-even cleaning count.
Open CalculatorConvert everyday length, actual volumetric flow, dynamic viscosity and kinematic viscosity units. For pressure, use the dedicated Pressure Unit Converter. For reference-state gas volumes, use the Standard to Actual Gas Flow Calculator.
Flow units in this converter refer to volumetric flow at one and the same pressure and temperature. Converting Nm³/h, Sm³/h or SCFM to actual flow requires a specified gas reference state and operating state.
Length: 1 inch = 25.4 mm exactly; 1 ft = 0.3048 m exactly. US liquid gallon = 3.785411784 L; 1 ft³ = 0.028316846592 m³. Dynamic viscosity: 1 cP = 1 mPa·s, 1 P = 0.1 Pa·s. Kinematic viscosity: 1 cSt = 1 mm²/s. Dynamic and kinematic viscosity are distinct; converting between them requires the fluid's density, which this converter does not infer. All values are unit conversions, not engineering design recommendations.
Convert absolute, gauge or differential pressure between Pa, kPa, MPa, bar, mbar, psi, atm and Torr.
