Abstract: A long throw Pop-Up Irrigation Nozzle assembly has no oscillating or rotating parts and includes a cylindrical body having a fluid inlet and a sidewall defining at least one fluidic circuit configured to generate a selected spray pattern when irrigation fluid flows through the body. In order to throw long distance, droplet velocity, droplet size and droplet initial aim angle determine the throw to provide a low precipitation rate (“PR”) for fluidic sprays. The nozzle assembly and method of the present invention achieve a PR of 1 in/hr or less and good spray distribution with a scheduling coefficient (“SC”) of about 1.5 without utilizing any moving components to provide a significantly more cost effective nozzle assembly, as compared to prior art rotator nozzles.
