WebChoked flow is a fluid dynamiccondition associated with the venturi effect. When a flowing fluid at a given pressureand temperaturepasses through a constriction (such as the throat of a convergent-divergent nozzleor a valvein a pipe) into a lower pressure environment the fluid velocity increases.

WebA sonic choke may provide a simple way to regulate a gas flow. The ratio between critical pressure and initial pressure for a nozzle can expressed as pc / p1 = ( 2 / (n + 1) )n / (n - 1) (1) where pc = critical pressure (Pa) p1 = inlet pressure (Pa) n = index of isentropic expansion or compression - or polytropic constant WebSep 7, 2010 · The geometry of the flow path has a direct bearing on the flow. For a converging/diverging nozzle, the choked plane forms at the minimum flow area. For example, in an isentropic flow in a De Laval nozzle, the critical pressure ratio is given by: (1) For air, with γ = 1.4, the critical pressure ratio is 0.528 and for steam (γ = 1.3), 0.546.
