WebThis particular rate is termed as the Critical Gas Rate, which is defined as Minimum Gas Rate required to lift the produced condensate liquid or water to the surface without liquid … Choked flow is a compressible flow effect. The parameter that becomes "choked" or "limited" is the fluid velocity. Choked flow is a fluid dynamic condition associated with the venturi effect. When a flowing fluid at a given pressure and temperature passes through a constriction (such as the throat of a convergent-divergent nozzle or a valve in a pipe) into a lower pressure environment the fluid velocity increase…

Webmaximum flow rate. The maximum flow rate is also known as choked flow or critical flow. Any further decrease in outlet pressure does not increase flow, even if the outlet pressure is reduced to zero. Consequently, high pressure drop flow only depends on inlet pressure and not outlet pressure. p 1 p 2 C v p 2 > 1/2p 1 T 1 q G g q = N 2 C v p 1 p ... WebCv (Flow Coefficient): The Cv is the number of U.S. gallons of water flowing during one min. at 60 Deg F through a restriction and the pressure drop through this restriction is 1 psi.
