Out of curiosity, how does the GPM flow increase, as pressure goes down?

How many sq ft is your yard? Do you have a well or city water?

New Sprinkler system

Installing a new system myself. Have yard all mapped out.
PSI= 60
GPM at 40psi = 5.4
GPM at 45psi = 4.2
GPM at 50psi = 3.7

Would appreciate suggestions regarding water pressure, types of rotors, risers, spray heads, valves, etc.
