Title: Drip irrigation hose with emitters having different discharge rates

Abstract: An improved drip irrigation hose is provided. The hose has a water supply passage and a plurality of flow regulating channels manufactured into the hose that are smaller than the water supply passage. The flow regulating channels each comprise a predesignated geometry to provide a desired discharge rate at a given pressure, an inlet section comprising one or more openings connecting the water supply passage to that flow regulating channel, and an outlet section comprising one or more openings connecting that flow regulating channel to the exterior of the hose. The plurality of flow regulating channels have at least two different geometries to provide at least two different discharge rates at the given pressure field. This invention has value to the irrigation designer in that it allows the designer to select emitter characteristics depending on the position of the emitter in the field.
