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 … WebAug 1, 2024 · In the field below, Area of orifice (A), the calculator will show you the area of the orifice. Proceed to enter the Coefficient of discharge (Cd). Next, enter the mean …
WebThe pressure across the pipe reduces as the fluid flows through an orifice. The fluid properties are also measured using this phenomenon. The orifice flow equation may be expressed as: The orifice flow equation yields the mass flow rate, or discharge Q, through an orifice, given the area of the orifice A. Q = Cd * A * √(2 * g * H)
