1 Resumo
O presente trabalho teve como objetivo determinar a importância da perda de carga localizada de um emissor tipo gotejador no dimensionamento da linha lateral, bem como comparar os resultados das equações que calculam a perda de carga localizada, além de verificar a influência de precipitados férricos, na perda de carga de uma mangueira gotejadora fabricada no Brasil. Como resultado obteve-se que a perda de carga representou 23% da perda de carga total, as equações apresentaram resultados significativos e a perda de carga aumentou em média 20% após o uso do sistema com água rica a em ferro.
Palavras-chave: Irrigação Localizada, Perda de carga localizada.

HEAD LOSS IN USED AND NEW HOSE DRIP LINES
2 Abstract
This paper aims to determine the importance of emitter´s local head loss in the hydraulic design of hose drip lines, as well as comparing the result of equations that calculate the local head loss; besides verifying the influence of iron precipitated at the hose head loss made in Brazil. The result found that localized head loss represents 23% of the total head loss; the equations showed significant results and the total head loss increased in an average of 20% after the irrigation system was used with water rich in iron.
Key Words: Drip irrigation, local head loss.
