Raio efetivo molhado e perfil de distribuição de microaspersores e difusores.

Abstract

It was evaluated the wetted effective radius and the water distribution profile of the Eindor, Fanjet-Black, Fanjet-Orange and the Microjet trickle irrigation emitters. The Eindor emitter presented a wetted effective radius compatible to the one provided by the manufacture. However, the others emitters presented different values, where the values for the Fanjet-Black and the Fanjet-Orange were, respectively, 40.76 and 26.74% higher, while for the Microjet it was 13.59% lower. The Eindor presented an uniform water distribution, while the others emitters concentrated the water application 1.0 to 2.28m farway from the emission point.
