Understanding Choked Flow of Gases


Medical equipment applications which handle various gas flows often require a precise, repeatable mass flow rate of gas. Our white paper explains the science behind “Choked Flow” or the condition when the velocity of the gas going through an orifice reaches the speed of sound. Also, we cover factors relating to flow that must be considered when choosing a precision orifice to achieve the desired result.
