http://dictionary.sensagent.com/Choked_flow/en-en/ WebAvoiding sonic flow. Single-stage restriction orifice limits pressure drop to avoid choking or sonic flow. Sonic flow normally occurs when the required pressure drop is higher than the critical pressure drop. If this is neglected, sonic flow creates noise and vibrations in the pipeline and can cause mechanical failure. Avoiding cavitation.
