Water volume/pressure loss on long pipe run

I've tried some of the online water flow thru pipe calculators, water pressure loss calculators, etc., but the results don't make sense (or more likely I don't understand what they are trying to tell me).

My water well puts out about 20 GPM at 50 PSI at the tank. I want to run a water line from the well tank to the front of my property (about 1500' total length). The land is flat. I plan to use 1" PVC buried.

What kind of volume/pressure can I expect at the far end? I'm hoping for at least 5 GPM at 30 PSI.

You would get about 5 to 10 psi. Move to a 2" pipe. Should be fine. Too much friction in a 1" pipe.
