Pressure Drop through plate screens

Pressure Drop through plate screens

Pressure Drop through plate screens

I have been dealing with pressure drop calculations through screen on bottom of reactor. In some of these cases I have had to deal with plate screen, elephant tools made of plate bars and some cases show up like a combination of screen cloth and plate screen.

The point is that some times we can use Kv (flow factor). This factor can be found as reference of filter and provided by the vendors. Massic flow, open area and Kv and done !!

What happen when I can not get this flow factor? I know Internet provides simple and useful softwares but I need to know what is the engineering fundament.

It is seems to be routine calc. I need to clear it up.

Thanks for your usual support


RE: Pressure Drop through plate screens

You may check with vendor any specific filter information, like flow rate versus pressure drop per
square area or efficiency curve to get accurate pressure drop estimation.    

RE: Pressure Drop through plate screens

Thanks silebilee !!!

Everything I was looking for I already found it in Section 6 "Fluid and Particle Dynamics" from Perry'Chemical Engineer Handbook.

On top of that I found additional information from "Resistance Flow Through Barriers Uniformly Distributed"
