I have a section of lawn that is 18 x 63. If I do sprinklers with 18 radius, that leaves me with good head-to-head coverage the short way, but either 9 feet short the long way, or sprinklers spaced about 21 apart, and not complete head-to-head coverage. Or adjust the sprinklers to shoot with 21 feet, but have serious over spray the short way. I was looking at using the Hunter mp2000 sprinklers for this project. Or is it best to go with smaller sprinklers,like the MP1000 and have them about 9 feet apart? i ffigured that would be 21 MP1000 or 8 MP2000, that is a big difference in matterial cost.

Flow is about 10 GPM and pressure around 60 PSI.

I have read tutorials, but they seem to only illistrate easy stuff, like 25 x 75 rectangles.

Thanks,

Michael
