WebAug 23, 2024 · Critical orifice plate. This is used to restrict flow by keeping the upstream pressure constant. This RO is sized for choked flow conditions. Generally, the thickness of the RO should be considered higher than the normal RO plates. Factors for sizing RO. The following factors should be considered when sizing RO. Pressure drop WebCritical (Choked) Pressure Drop. With choked flow and critical pressure drop, the outlet pressure - p o - after the control valve is aprox. 58% of the inlet pressure - p i - before the control valve. The flow coefficient at choked - or critical - flow can be expressed as: C v = m / 1.61 p i (2) where. m = steam flow (lb/hr) linearity in design https://craftedbyconor.com
