Thank you for the follow up. Regarding zone 1, does it sound like I'm calculating the precip. rates correctly?
- 1.5 LA nozzle @ 40 psi has a radius of about 30 ft. per the spec. sheet. If I want it at 25 ft., I divide 25 squared by 30 squared, giving me 0.65. Then divide 1 by 0.65 and multiply by the spec'd precip. rate of 0.31 inch/hour to arrive at 0.48 in/hr, then of course multiply by 2 since it's a corner sprinkler to end up at 0.95 in/hour.
Regarding zone 2, not sure I'm understanding - I modified and attached a new layout, having deleted out two heads and adding two heads. I don't want overspray onto the driveway or house/flower beds, so this makes it a little tougher also. Thanks [img]https://www.dropbox.com/s/hxs2vbclin6chu1/Head%20layout.pdf?dl=0[/img]
Trade in the 3500 heads for 5000 series, would be my first thought. Better nozzle selection, especially low-trajectory-angle sprays, for windy conditions. Don't worry about that supposed gap you see, and for which you want to add a sprinkler. There is enough overlap, and you could always upsize one or more of the corner nozzles, if you wanted heavier coverage there. The zone with the big tree is more complicated. I will assume you don't want to try to dig anywhere close to it. That would have you adding one more head, and spacing them so that the tree is about ten feet away from any of the heads nearest to it.
