Caracterização hidráulica de um tubo gotejador.

Abstract

It was studied the hydraulic characteristcs of Rain Bird drip tape. This drip tape is a flexible emitter with long path, with turbulent flow and spacing 0,30 m. Is was used different tests in order to determine the hydraulics characteristics. The value of uniformity and amitter discharge exponent agree with the manufacturer. The internal diameter increased with pressure and the rupture resistence failed at 21 m.c.a. The value of head loss factor (F) decrease with the pressure increasing at the same number of emitters.
