ABSTRACT:
Drip tape for below or above ground irrigation includes a sheet of material formed into a tube by overlapping opposite side edges of the sheet and bonding the side edges along a longitudinal seam thereby forming a primary flow path. A strip of transparent material is bonded to an interior surface of the sheet prior to seaming, at a location remote from the longitudinal seam so as to define, in combination with the tape wall, a plurality of secondary flow paths within the primary flow path. Each secondary flow path includes an inlet region, a turbulence inducing region and an outlet region; the inlet region including a plurality of inlets in the second strip connecting the primary flow path to the secondary flow path upstream of the turbulence inducing region; the outlet region including an outlet in the tube connecting the secondary flow path to atmosphere downstream of the turbulence inducing region.
