WebChoked flow is a phenomenon that limits the mass flow rate of a compressible fluid flowing through nozzles, orifices and sudden expansions. ... For the conditions at the choke point this value is known as the … WebChoked flow usually happens when there is a high pressure drop across the valve. Choked flow begins when a pressure ratio is reached (1.8 for methane) and the gas velocity is at Mach 1 (767.2 MPH). There does not need to be a high flow rate for choked flow to occur. The valve is "choking" the flow back because it has reached sonic flow (Mach 1 ...
