Desempenho hidráulico de emissores tipo microaspersor e difusor.

Abstract

It was studied the hydraulic performance of trickle irrigation emitters. The analyses was based on the manufacturing variation coefficient and the characteristic equation. The emitter types tested were the Eindor, Fanjet-Black, Fanjet-Orange and the Microjet. The results showed that the Eindor, Fanjet-Black and Fanjet-Orange emitters are excellents in their manufacturing qualities, while the Microjet emitter showed to be of a reasonable quality. The power type characteristic equations resulted in correlation coefficients (r2) around 0.99.
