Última Modelling head loss along emitting pipes using dimensional analysis REA Perboni,Acácio; Frizzone,Jose A.; Camargo,Antonio P. de; Pinto,Marinaldo F.. Local head losses must be considered in estimating properly the maximum length of drip irrigation laterals. The aim of this work was to develop a model based on dimensional analysis for calculating head loss along laterals accounting for in-line drippers. Several measurements were performed with 12 models of emitters to obtain the experimental data required for developing and assessing the model. Based on the Camargo & Sentelhas coefficient, the model presented an excellent result in terms of precision and accuracy on estimating head loss. The deviation between estimated and observed values of head loss increased according to the head loss and the maximum deviation reached 0.17 m. The maximum relative error was 33.75% and only 15% of the data set... Tipo: Info:eu-repo/semantics/article Palavras-chave: Microirrigation; Lateral line; Maximum length.
