As the incompressible steady-flow fluid passes through the orifice, pressure builds up due to flow restriction, causing the fluid velocity to increase according to Bernoulli’s equation. Where: WebOrifice plates are most commonly used to measure flow rates in pipes, when the fluid is single-phase (rather than being a mixture of gases and liquids, or of liquids and solids) …
WebHagen–Poiseuille equation. In nonideal fluid dynamics, the Hagen–Poiseuille equation, also known as the Hagen–Poiseuille law, Poiseuille law or Poiseuille equation, is a physical law that gives the pressure drop in an incompressible and Newtonian fluid in laminar flow flowing through a long cylindrical pipe of constant cross section. WebOct 3, 2024 · Because we know the inner diameter of the annulus (the pintle body OD), and the properties of the liquid flowing through the reservoir leading to the injector orifice, we were able to calculate an …

Saturated … WebVenturi flow meters, like all other types of differential pressure flow meters, function on the principles of the Bernoulli equation, which states that as the speed of the flow of a fluid increases, pressure loss occurs. Venturi tubes are available in sizes up to 72” and can pass 25 to 50% more flow than an orifice with the same pressure drop.
