Orifice Sizing Principles - chemicalengineeringnow

Orifice Sizing Principles. An orifice meter is a device used for measuring the rate of fluid flow. It uses the same principle as a Venturi nozzle, namely Bernoulli's principle which says that there is a relationship between the pressure of the fluid and the velocity of the fluid. When the velocity increases, the pressure decreases and vice versa.Orifice equation Engineering FandomThe orifice equation describes the rate of flow of liquid through an orifice. The equation can be represented as where Q = flow (cubic metres per second) = coefficient of discharge A = area of orifice (square metres) g = acceleration from gravity (9.81m/s^2) h = head acting on the centreline (m) For a circular orifice, the equation becomes Typical values for the coefficient of discharge are Orifice Plate with Concave Smooth Gritted Surface TreatmentOrifice plate - WikipediaAn orifice plate is called a calibrated orifice if it has been calibrated with an appropriate fluid flow and a traceable flow measurement device. Plates are commonly made with sharp-edged circular orifices and installed concentric with the pipe and with pressure tappings at one of three standard pairs of distances upstream and downstream of the plate; these types are covered by ISO 5167 and other major standards.
