Spray Starch System for Pulp and Paper

mjar1989

At our recycled paper mill we are planning to install a spray starch system to help with ply-bond .

The basic idea is to feed 14 % starch slurry and recycled water into a centrifugal pump. The diluted slurry then runs through rubber hosing, valves, filter, the shower bar and then returns to the inlet of the centrifugal pump to be recirculated.

How can I estimate:
1) Pressure drop across the shower bar
2) The filter/screen
