Enter an airflow and a design criterion, and the duct size appears instantly, computed from ASHRAE Fundamentals duct-design methods. SIZE MODE • Enter airflow plus either a friction rate or a target velocity • Exact round diameter, plus the nearest standard size (EN 1506 and imperial) • Rectangular equivalent — give one side, get the other (Huebscher) • Actual velocity, friction rate, velocity pressure and Reynolds number ANALYZE MODE • Enter airflow and an existing duct — round diameter or rectangular a×b • Instantly see velocity, friction rate, velocity pressure and Reynolds number • Check an existing run against design limits before you order material REAL ENGINEERING, NOT A LOOKUP TABLE • Colebrook–White friction factor, solved iteratively — not a chart approximation • Duct material roughness: smooth, galvanized steel, lined, flex, rough • Standard air, or your own custom density • Hints for typical design ranges, and warnings for high aspect ratio or laminar flow UNITS THAT FIT YOUR OFFICE • SI and IP throughout • Airflow in L/s, m³/h or CFM, chosen independently WORKS ANYWHERE • 100% offline — no account, no sign-up, no internet connection • No ads, no subscription, no tracking, no data collection • One single purchase, yours for good Available in English, Japanese, Simplified Chinese, Korean, French, German, Spanish and Vietnamese.
