Avaliação do desempenho hidráulico do gotejador Carborundum-GFT.

Abstract

The purpose of this work is to evaluate the GFT model Carborundum hydraulic drip performance. Therefore were analyzed the manufacturing variation coefficient and the characteristic equation of the discharge-pressure relation. The manufacturing variation coefficient was 0.024, which is considered excellent by the ASAE classification. By the statistic point of view, the data showed a normal distribution model. The discharge variation in relation to its average revealed a normal model distribution. The adjustment of the discharge versus pressure tested data resulted in a q=0,234*H0,603 characteristic equation, with a determination coefficient (R2) equals to 0,9976 and the flow regimen was considered partially and unstable.
