Restriction after control valve
Restriction after control valve
(OP)
Hi,
I have an installation with restrictions after control valves and I'm looking to calculate pressure drop vs flow for all of them. The type of restrictions are:
1) Perforated plates with various amount of holes and hole diameter
2) Tank diffuser, pipe extends into tank and has large number of holes in the wall
The medium is condensate (flashing/non-flashing), steam and in some cases two phase flow (steam+condensate).
Does anyone know any reference (book/paper/standard..) which could be used for these calculations as well as design of new similar restrictions?
thanks
