As the name suggests, function of a restriction orifice is to restrict the flow and kill pressure downstream of the orifice. The restriction orifice size for given flow and downstream pressure limit can be calculated usingEnggCyclopedia's restriction orifice sizing calculator for gasesandEnggCyclopedi...
Restriction orifice sizing (by design engineer or vendor) Checking of critical design elements like cavitation index (Kc=0.93), pressure drop, minimum orifice diameter, allowable space in piping routing, etc. Filling out the necessary information in P&ID and RO datasheets Installation of Restriction ...
How can restrict orifice limit the flow rate? I mean when it is installed to the pipe the flow rate will constant regardless of upstream or downstream pressure, is that right or not? 2)And when sizing the restriction orifice, is it used the same equation for sizing orifice plate? Thanks...
