1 RESUMO
O presente trabalho teve como objetivo determinar a vazão dos gotejadores, a curva relação vazão-pressão, a sua equação característica, o coeficiente de variação de vazão (CVQ), e também avaliar a uniformidade de aplicação de água, do tubo gotejador da marca Netafim, modelo Tiran 17, utilizado para a irrigação com esgoto doméstico tratado. Após 1000 horas de uso do tubo gotejador, o entupimento de gotejadores reduziu a uniformidade de aplicação de água de 98% para valores menores que 60%, e aumentou o coeficiente de variação de vazão a valores maiores que 0,29.
UNITERMOS: coeficiente de variação de fabricação, reúso de água

2 ABSTRACT
This paper aimed to determine the flow rate of drippers, their “flow rate-pressure” curve, their equation, their flow rate variation coefficient (VCq), as well as to evaluate the uniformity of water application of the Netafim drip pipe,Tiran17 model, used for irrigation with domestic wastewater from treated household drain. After 1000 working hours, the blockage of some drippers decreased the uniformity of water application from 98% to lower than 60% and increased the flow variation coefficient to values higher than 0.29.
KEYWORDS: flow rate variation coefficient, wastewater
