Flow rate through orifice
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) WebFor compressible fluids flowing through a square-edge orifice with D and D/2 taps, an empirical expression for Y is given as [3] (18) where is the specific heat ratio (= 1.4 for …

WebIn this present paper, the commercial Computational Fluid Dynamics (CFD) is used to predict the flow features in the orifice flow meter. Outcomes of the CFD simulations in terms of profiles of velocity and pressure are discussed in detail. It is observed that the f
WebTo write this as a proportionality, we relate flow rate ( Q) to pressure ( P) as follows (the constant k accounts for unit conversions and the geometries of the orifice plate and pipe): P = k Q 2. This is a practical problem for us because our intent is to use pressure measurement ( P) as an indirect (inferred) indication of flow rate ( Q ). 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 …
