I was wondering if there's a way to account for multable nozzles, ex. 40 spray nozzles on a zone
The number of sprinklers on a zone is irrelevant since Iro's custom nozzle input only accepts a precipitation rate in inches/hour.
Thanks for reaching out @dks2768
@ronjonp pretty much summed it up. If you would like reference this article we discuss how precipitation rates work.
If you have any additional questions feel free to let us know.
