Strainer back pressure
Strainer back pressure
(OP)
Can anyone suggest a calculation method to determine the pressure drop for a fluid through a 10x10 strainer mesh?
Viscosity: 200cp
Flow: 180 GPM
Velocity 8 ft/sec
Tube dia: 2.875 ID
Screen 56% open area
The screen is formed into a vertical basket with a 4" dia flat end. It is 16" long and 9" dia at the basket open end. The strainer is inside a 10"dia x 18" long canister.
Thank in advance for any help
Doug

The Hayward Strainer web page might be useful for you:

For the Cv factor, depending on what kind of strainer you have, it might be available on the Hayward site. For example, some Cv's are listed at the bottom of:

This formula is what I need, unfortunately, I am using a made-up strainer so I have no simple way of arriving at a Cv. I need to calculate that value.

I'm thinking with something like the formulas in Crane you should be able to come up with a 'K' or 'Cv' term and then stick in your process conditions.
