I have 100 foot by 100 foot with equals 10,000 square feet. I
want to water this area without putting any sprinklers in the
middle. All sprinklers will be on the outside perimeter. Now I
will put a sprinkler shooting 50 feet in the middle of all 4
sides. This will work. The only problem is half my lawn is
getting twice as much as the other half. I can put a 10 foot
diameter in the middle and put a sprinkler network there. But I'm
not sure which the best way is. Any ideas?

If you're running 400 feet of line on one valve you might need to
increase pipe size. Alternately, you could run two valves with 200
feet of pipe each. Reduce frictional loss.
I would put a couple of 360 pop ups on the center line.
