Abstract
A drip irrigation hose includes a tube for conducting pressurized water through its interior and formed with a plurality of outlets for emitting water at longitudinally-spaced locations along the length of the tube; and a plurality of flow-control elements fixed with respect to the inner surface of the tube at longitudinally-spaced locations thereof to define, with the inner surface, a plurality of labyrinths each having an inlet communicating with the interior of the tube and an outlet communicating with a tube outlet for emitting water there from at a slow rate. The labyrinth includes a bottom wall constructed to produce, adjacent to the bottom wall, a significant laminar flow of water in which the laminar flow decreases, and thereby turbulent flow increases, with an increase in the water pressure within the tube to thereby provide pressure-compensation for the water flow through the respective tube outlet.
