AIR FLOW - Duct and Fan Analysis.

MSDOS (will run in an MSDOS window [click here for MSDOS NOTES] under Windows).

AIRFLOW helps HVAC engineers quickly select duct and fan sizes. It calculates direct velocity and pressure as well as brake horsepower requirements under standard and non- standard conditions. Included are built-in formulas for applying temperature and altitude corrections. Also provided are duct roughness corrections which are sometimes necessary for treating nonstandard situations. AIRFLOW analyzes square, rectangular, and round ducts. Typical inputs are duct length, desired airflow rate, temperature, altitude, duct cross section, friction factor (default or from internal tables), and fan efficiency. A unique spreadsheet-like recalculation feature allows you to selectively change any input variable to obtain new solutions. Using this feature, you can quickly arrive at a practical specification.

AIRFLOW includes a 30-page manual. Standard English units are used.
