Resumo: In sprinkler irrigation, the water is precipitated artificially. In this system, the distribution efficiency is subject to the characteristics of the sprinkler, pressure, operating flow, external factors such as wind and temperature, type of arrangement and stem height. In view of the above, this study aimed to evaluate the Coefficient of Uniformity Christiansen - CUC, Coefficient of Uniformity of Distribution - CUD and Coefficient of Statistical Uniformity - CUE in low flow sprinklers under the quadrangular, triangular and rectangular arrangements, for height of rod of 1,50 and 2,00 m under low pressure of 10 mca. The NDJ 5022 sprinkler presented coefficients up to 80% for all arrangements and overlays, with a triangular arrangement that presents the best installation cost.

Nesse sistema, a eficiência de distribuição está sujeita às características do aspersor, pressão, vazão de operação, fatores externos como vento e temperatura, tipo de arranjo e a altura da haste. Diante do exposto, objetivou-se com este trabalho avaliar o Coeficiente de Uniformidade Christiansen - CUC, Coeficiente de Uniformidade de Distribuição - CUD e Coeficiente de Uniformidade Estatístico - CUE em aspersores de baixa vazão sob os arranjos quadrangular, triangular e retangular, para altura de haste de 1,50 e 2,00 m sob baixa pressão de 10 mca. O aspersor NDJ 5022 apresentou coeficientes acimas de 80% para todos os arranjos e sobreposições, sendo arranjo triangular o que apresenta melhor custo benefício de instalação.Editora Verde2019-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/601610.18378/rvads.v14i2.6016Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 14 No. 2 (2019); 170 - 180Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 14 Núm. 2 (2019); 170 - 180Revista Verde de Agroecologia e Desenvolvimento Sustentável; v. 14 n. 2 (2019); 170 - 1801981-8203reponame:Revista Verde de Agroecologia e Desenvolvimento Sustentavelinstname:Grupo Verde de Agroecologia e Abelhas (GVAA)instacron:GVAAporhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/6016/6173https://www.gvaa.com.br/revista/index.php/RVADS/article/view/6016/5782Copyright (c) 2019 Leôncio Gonçalves Rodrigues et al.info:eu-repo/semantics/openAccessRodrigues, Leoncio GonçalvesNery, Aparecida RodriguesSousa, Francisco Rondynelle RodriguesRodrigues, Luis Nery2021-06-14T13:13:32Zoai:ojs.gvaa.com.br:article/6016Revistahttps://www.gvaa.com.br/revista/index.php/RVADS/PUBhttps://www.gvaa.com.br/revista/index.php/RVADS/oairvadsgvaa@gmail.com || patriciomaracaja@gmail.com || revistaverde1@gmail.com || suporte@antsoft.com.br1981-82031981-8203opendoar:2024-03-06T12:59:30.134783Revista Verde de Agroecologia e Desenvolvimento Sustentavel - Grupo Verde de Agroecologia e Abelhas (GVAA)false
