WebFlow rate measurement with Bernoulli equation. The Venturi flow meter exhibits relatively low pressure loss, in addition to having a simple design and being inexpensive to manufacture. The most precise flow meter among the tube type flow meters, i.e., the orifice, nozzle and Venturi meters, is the Venturi flow meter [5]. The Venturi flow meter ... WebTheory: - From the continuity and Bernoulli equations, derive the equation for the ideal flow rate through a venturi tube and orifice as a function of the pressure difference at two locations and diameters at two locations. - Explain the discharge coefficient.
WebVertical Orifices and Nozzles For orifices and nozzles installed in vertical piping, with elevation change \Delta z = z_ {1} - z_ {2} Δz = z 1 − z 2, the following head loss and flow rate equations may be used: Expansion … WebWhen flow measurements of incompressible fluids are made, the expansion factor Y equals unity. For compressible fluids flowing through a square-edge orifice with D and D/2 taps, an empirical expression for Y is given as [3] (18) …
WebMar 5, 2024 · 5. Equipment. The following equipment is required to perform the orifice and free jet flow experiment: F1-10 hydraulics bench; F1-17 orifice and free jet flow apparatus, with two orifices having diameters of 3 and 6 mm; Measuring cylinder for flow measurement; and. Stopwatch for timing the flow measurement. 6. 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 ).
WebNov 15, 2002 · Frequently the fluid flow Q through an orifice is assumed to be proportional to the square root of the pressure drop across the orifice Δ p. (1) Q=c d A 2 ρ Δ p sign ( Δ p) (In Eq. (1) cd denotes the discharge coefficient, A is the cross-section area of the restriction.) This formula strictly holds for an incompressible steady-state flow.
