Compressed Air Main Velocity Checker
Check compressed air main velocity against the recommended 6–9 m/s design window for the duty.
Compressed-air headers target 6–9 m/s at line conditions; faster mains carry condensate into tools and drop pressure.
Formula
Compressed Air Main Velocity Checker is a free compressed air main velocity for process, mechanical and water engineers — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Compressed Air Main Velocity Checker
Check compressed air main velocity against the recommended 6–9 m/s design window for the duty. The calculation implements V = Q / A = 4·Q / (π·D²) (CAGI Compressed Air & Gas Handbook). Compressed-air headers target 6–9 m/s at line conditions; faster mains carry condensate into tools and drop pressure.

Frequently asked questions
What formula does the Compressed Air Main Velocity Checker use?+
It computes V = Q / A = 4·Q / (π·D²), per CAGI Compressed Air & Gas Handbook. The formula is displayed under the result.
What should I keep in mind when using this calculator?+
Compressed-air headers target 6–9 m/s at line conditions; faster mains carry condensate into tools and drop pressure.
Does this work for any fluid?+
Yes — density and viscosity are inputs (with common fluids suggested in the field hints), so the same physics applies to water, oils, gases and process fluids. Compute always runs in SI internally, so unit mix-ups can't corrupt the result.
Is the Compressed Air Main Velocity Checker free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
