Aight For the guys who know more about this type of stuff .
Ive got 300 foot half inch of sch 40 pvc I need to run a line 125 foot to the the house from a well . The well puts out 6gpm. 40 on 55 off psi Its a jet pump thats as high as it goes so cant turn it up any higher. I used a calculator for figurein. At 6 gpm it shows 19.9536psi drop 6.33453 ft/sec and at 3gpm it showed 5.45136 psi drop and velocity at 3.16726 ft/sec

A 1 inch line is comein from the pump to the pressure tank and to a outlet.

If i ran 2 lines of 1/2 pvc 6gpm at the house would both lines get around 3 gpm and give me my 50 psi . I know that bigger pipe is better suited . But with 300 foot of pipe . Its just layin in my yard so i can put it to use.
