Restriction Orifice Sizing problem


Thread Starter


Dear All,

I'm having problems figuring out how to size restriction orifice plates. Actually what my basic requirement is to find the sizing parameters for a restriction orifice which would give me a permanent pressure drop of 3-4 bars across it.

The fluid is basically boiler feed water (de-min) at 33 bars.
The temperature is 115 deg centigrade.
The discharge line size of the pump is 2" and the pump is multistage-centrifugal type.

I'm not quite sure how to start with doing this... can you guys please guide me???

Best Regards,
