pressure calculation
(OP)
In my process, cement ( polymer) is pumped through a filter to a coagulation tank at at rate of 20 gpm. The pipe size is 3" and the cement distributes through 12 nozzles each of 1/8" dia to the coagulation tank. Filter inlet and outlet pressures are about 28psig and 24 psig respectively.
We change these filters frequently ( 1.5 months)when the DP hits 25psig. At this DP the pump runs close to its trip pressure ( 70psig) so i decided to increse the feed nozzle size from 1/8" to 3/16" and increase the filter span but I do not by how much I can increase the filter life. How can I calculate the pressure in the line or filter outlet? We maintain 8psig in the tank. Your suggestions are hihgly appreciated. Thank You

I dont know if you have tried some instrumental solutions, like some transduction,or some sensors, which temperature the polymer is? you dont have any temperature drop between your tank at 8psig and your nozzles?

A Delta P of 25 is too much IMO. Use 10 psi.
What is more important the pump or the filter?
You need a new filter
