It's a hard concept to visualize, but the pumps themselves do not create any pressure...
They are rated at the GPH they can flow at a given "head"...
It's the "head" (or restrictions) that cause the pump to opperate under "pressure"
That's why a Mag 5 (for example) will flow 500gph at 0 head 380 gph at 3' head 250 gph at 5' head and only 20 gph at 10'...
If you know the pump model and the "head" you will be opperating at there is a way you can figure the psi/pressure it will be opperating at...
For the above example Mag 5 @ 5' head with 1" line opperates at 2.21 psi...

The "formula" is in the form of an on line calculator...
Need to enter information to calculate head and pressure...
Line size, # 90deg elbows, 45 deg elbows, valves, outlets, vertical lift, horizontal flow legnth,etc...
For the the Rio at 0 (?) head with a 1' outlet you will only get 630 gph at .15 psi...
What are you trying to figure "pressure" for...??
