Screwed strainers How to use:
For a given flowrate extend a horizontal line until it intersects with the diagonal that represents the strainer size and material. Drop a vertical line from this point until it reaches the pressure drop axis. This figure indicates the pressure drop in bar, e.g. 9 000 kg / h of water passing through a 1½" Fig 14 with standard screen would have a pressure drop of 0.047 bar.
