Abstract
The serpentine, turbulence inducing path lengths from the inlets to the outlets of the flow regulating passage of a continuous emitter drip irrigation hose are arranged in back to back fashion relative to the outlets in the sense that the chevrons angle away from each of outlets, so there is parallel turbulent flow from two inlets to each outlet. This doubles the flow rate from each outlet without changing the dimensions of the flow regulating passage.
