Flow of gas through orifice
WebWhen gas flows through an orifice it is subject to a throttling process. This results in the gas temperature changing to an extent determined by the pressure drop. Many of the common gasses will be chilled by throttling, although some gasses will increase in temperature. A positive Joule – Thomson coefficient, which is a function of both ... WebChoked 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 …

Webwhere k is the specific heat ratio of the discharged gas. For many gases, k ranges from about 1.09 to about 1.41, and thus. ranges from 1.7 to about 1.9. which means that choked velocity usually occurs when the absolute source vessel pressure is at least 1.7 to 1.9 times as high as the absolute ambient atmospheric pressure.
