Orifice plate in fire fighting system
Witryna12.2 Orifice Plates 12.2.1. An orifice plate used to hydraulically balance an installation, or to accommodate pump characteristic, shall: have an orifice diameter not less than one-half of the internal diameter of the pipe into which it is fitted; be fitted only in pipes of 50 mm nominal bore or greater; WitrynaThe orifice plate installed in the pipeline causes an increase in flow velocity and a corresponding decrease in pressure. The equation that governs the use of these devices will be Bernoulli's equation in case of incompressible flows (liquids) or the first law of thermodynamics in compressible flows (gases).
