Thanks for the replies, but I'm still confused. Please be patient, I will have my system installed one of these days. During my research over the weekend I discovered that when sizing flow rates of rotors always remember that the 1/4 is going to put four times the amount of water over that small area as the full circle nozzle in the same amount of time. (Once again, back to the graph paper and compass) So I'm guessing 0.9 gpm 1/4, 1.8 gpm 1/2, and 3.60 gpm for full circle. Would you agree? Also in my original question, I'm still not clear on the what psi to calculate my flows/distance with, 25psi or 35psi, based on my design psi & flow, the way I see it, I'll get one flow rate w/25 psi and another w/35psi and I don't want to flow more gpm than my design flow (my design flow is 15gpm @ 50psi). Just one more question, ("I know your getting tired of reading") on the lateral pipe material. Do you suggest sch 40 PVC or Class 200 PVC? Thanks again.
