WebSep 21, 2024 · Sonic Flow- When sizing a RO for gas service, sonic flow is a key consideration. Sonic flow may happen and choke may happen when the necessary pressure drop is greater than the critical pressure drop. Sonic flow in a pipeline will cause noise and vibration, and because of the vibration, mechanical failure risks will rise. WebWhen the gas velocity is choked, the equation for the mass flow rate is: or. Where the ratio of the absolute source pressure to the absolute downstream ambient pressure is less than [ ( k + 1 ) / 2 ] k / ( k - 1 ) , then the gas velocity is non-choked (i.e., sub-sonic) and the equation for the mass flow rate is: or
