Flow limiting orifice

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… WebThe diagram below indicates steam flow rate (lb s /hr) through orifices ranging diameter 1/32" to 1/2" and 2 - 300 psig steam line pressure.
