To find the pressure drop, enter the chart at 1,000 GPM and intersect the line representing a 6" FV Strainer. Read to the left to intersection of SG = 1. Follow diagonal guide lines down to SG = 0.6. Read straight to the left for the corrected pressure drop. In the example, the FV Strainer would have a pressure drop of 0.7 PSID. The strainer section would depend upon piping configuration and allowable pressure drop.
