WebbOrifice. In fluid mechanics, an orifice is a plate that is inserted in a line and typically has a round hole in its centre. Orifices are used as fixed throttles that generate head loss. The … WebbThe orifice offers a restriction to the process flow and the pressure head drops from the upstream to the downstream. The permanent pressure loss by the device is the intended pressure drop for which it is sized. The area of the orifice determines the rate of flow at the outlet of a given process fluid for the specified pressure and temperature.
