Could someone explains how the pressure drop across the strainer/control valve/flow elements are calculated?

Hi ,

If you are a chemical engineer you should refer to your textbooks .

 

To support your work you should consider to get a copy of the famous Flow of Fluids through valves, fittings and pipe from Crane , also known as Technical paper N0 410 M .

 

A few links from internet .

Note : You could also use the search engine in this forum , in particular check for Aioflow a software developed by Katmar, a member of this forum .

 

Good luck

Generally these are finalised based on the pressure drop available in the system.

 

If it is pump circuit, it is good engineering practice to use pressure drop of control valve and flow instrument (orifice) as 0.7 bar and 0.25 bar respectively.
