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.

The other thing that you didn't think of is that impact sprinklers and gear
driven sprinklers that can throw water 50 feet out also do a horrible job of
watering directly infront of the sprinkler. So there will be a 5-10' radius
of under watered as well. The way to over come this is to put 1 sprinkler in
the 4 corners, and in the middle of each side as well.

As someone else pointed out, you probably don't want to run 3/4" pipe down
the entire run, the pressure loss and flow rate will be too low for the
desired results. Use 1 1/2" pipe for your main runs.
I assume the reason for the "overwatering" is the fact that
the 180 degree sprinklers in each side OVERLAP, and NOT
because of pipe size or pressure drop...
Why not consider four 90 degree heads, all in the center,
facing each side.?"??? That should get rid of the overlap and use
the same amount of water......
Just an idea...

You will not have much luck with your 100% overlap which you need on
windy days. Run your 4 sprinklers down the middle and do it right. It
is too difficult to reinstall the center line after you have installed
