Your question is incomplete!
To even calculate the pressure losses needs more info.
What is the pressure at the tapping? Is there any elevation rise to the final outlet?
What do you need in pressure & flow at the outlet?
I have seen a water line run 1 mile in 1/2″ copper & the pressure would rise to the tapping pressure after 1/2 an hour but when the outlet tap was opened, not a drop issued out of the tap.
