MATHEMATICAL MODELING OF FLUID FLOW THROUGH MULTIPLE ORIFICE AND …
Orifice 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) and well-mixed, the flow is continuous rather than pulsating, the fluid occupies the entire pipe (precluding silt or trapped gas), the flow … Zobacz więcej An orifice plate is a device used for measuring flow rate, for reducing pressure or for restricting flow (in the latter two cases it is often called a restriction plate). Zobacz więcej Incompressible flow By assuming steady-state, incompressible (constant fluid density), inviscid, laminar flow in a horizontal … Zobacz więcej • Accidental release source terms • Choked flow • De Laval nozzle • Flowmeter Zobacz więcej An orifice plate is a thin plate with a hole in it, which is usually placed in a pipe. When a fluid (whether liquid or gaseous) passes through the orifice, its pressure builds up slightly … Zobacz więcej Flow rates through an orifice plate can be calculated without specifically calibrating the individual flowmeter so long as the construction and installation of the device complies with … Zobacz więcej Witryna1 sty 2015 · This chapter considers the expansibility-factor equation for orifice plates, its history, the new data collected at the same time as the discharge-coefficient equation was revised, the analysis, the equation in ISO 5167-2:ISO 2003, a theoretical model and subsequent work in the US to derive the equation in API 14.3.1:2012. Witryna5 sie 2016 · The orifice plate flowmeter, the most common of the differential pressure (DP) flowmeter family, is also one of the most common industrial flowmeters. It is apparently simple to construct, being made of a metal plate with an orifice that is inserted between flanges with pressure tappings formed in the wall of the pipe. a部詳細 英語
