WebFor a given pressure drop across the restriction, Y is constant and thus does not change during the iterative calculation process used to calculate the actual flow rate (only Cd is a function of flow rate). Figure 2. Orifice Meter With D and D/2 Taps Manometer Fluid The fluid in all of the manometers is Meriam D-2673 Red Oil. 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) WebCalculations. The relationships for flow rate, pressure loss and head loss through orifices and nozzles are presented in the subsequent section.

WebJun 8, 2024 · Flow rate is directly proportional to the square root of pressure. So for any given orifice, all else being equal, $\frac{GPM}{\sqrt{PSI}}$ is constant. Technically PSI here is the pressure difference across the orifice, but with no backpressure only the input pressure matters. For an orifice rated 1.8 GPM at 90 PSI, $\frac{GPM}{\sqrt{PSI}} = 0 ... WebChoked flow is a compressible flow effect. The parameter that becomes "choked" or "limited" is the fluid velocity.
