Pressure drop thru Screen

[saab007]

I am trying to calculate the pressure drop through a screen member inside a pipe. I have beed recommended to base it on a model of an orfice and to reference Cranes. I was wondering if any one else might be able to a recommend a different model or might have some different references.

Thanks in advance.

The ASHRAE Handbook of Fundamentals (or maybe one of the other handbooks) has data for screen flow with air. It's been a while since I looked at it, but it is based on just percent open area. IE, the mesh size doesn't enter into it, which implies it's based on orifice flow.

Find a copy of "Handbook of Hydraulic Resistance," by I.E. Idelchik. Chapter 8, "... Resistance Coefficients of Grids, Screens, Porous Layers, and Packings."

The Chemical Engineers' Handbook has an orifice -type equation too. It's on page 5-37 in my 5th Edition.

Good luck,
