You can calculate the approximate clean pressure drop, inlet velocity, & screen velocity for your intended flow rate and Specific Gravity (Sg) by replacing the default (max) values below (green boxes) with the design values.  The Sg of Water is 1.
 (The screen velocity and straining ratio are based upon the standard perforated basket and its' % open area. Use our calculations page to generate data for other perf or mesh sizes. Max. PSI based upon 100F max. temperature.)
