Air flow rate and effective cross-sectional area calculator

HOME > Technical information > Air flow rate and effective cross-sectional area calculator

Estimate air flow rate.(Composite effective cross-sectional area can be estimated as well.)

STEP1 > Enter effective cross-sectional area.

STEP2 > Enter the pressure value and the temperature.

Flow rate estimation of subsonic flow requires downstream pressure input.
Without entering downstream pressure, choked flow (Max. flow rate) shall be estimated.
