Drip irrigation hose with emitters having different discharge rates

摘要

An improved drip irrigation hose 10 has a water supply passage 26 and a plurality of flow regulating channels 24 that are of a predesigned geometry so as to provide a desired discharge rate at a given water pressure. The flow regulating channels have at least two different geometries to provide at least two different discharge rates at a given pressure. The design ensures that water passing through the hose, having a higher pressure at the end connected to the water source and a lower pressure at the furthermost end of the hose, is emitted at a more uniform rate along the length of the hose.
