This pressure drop chart is based on the flow of clean water through the Keckley Fabricated Basket strainers with 1/8" screen perforations.
TO USE CHARTS:
Find your desired rate of flow (GPM) on the left hand side of the chart. Follow its corresponding horizontal line to the point where it intersects the diagonal line indicating the strainer pipe size. From this point of intersection, follow the vertical line down to the bottom of the chart to determine the approximate pressure drop.
CORRECTION
FACTORS:
For finer mesh screens that are backed with a perforated sheet, multiply the pressure drops shown at right by the following:
40
mesh x 1.2
60
mesh x 1.4
80
mesh x 1.6
100 mesh x
1.7
