Resumo: | Aiming higher efficiency in irrigation pipelines projects several studies are done mainly about hydraulic characteristics of these systems. However, even hydraulically that’s right, the project can’t answer economic aspects. This context the working gift aimed make hum hydraulic and economic study on the flow rate of the water mains in galvanized steel and PVC. It was considered a standard pipeline, composed by suction pipe, pump set, connection system and protection and discharge piping, operating with flow rates of 50, 100, 150, 200, 250 and 300 m³ h-1 and nominal pressures of 80, 125 and 180 mca, operating time function, the total geometric drop, energy cost of pumping and piping of the acquisition. There was that steel pipes galvanized the economic speed varied among 0.88 and 2.65 m s-1 and PVC pipes, between 0.68 and 2.54 m s-1. It can be concluded that value of economic speed and decreases with the increase in the rate of operation of the pipeline and the increase in total drop geometric. The economic speed was indirectly influenced hair increase in energy tariff and directly influenced hair increased pipe cost. |

No entanto, mesmo que hidraulicamente correto, o projeto pode não atender aspectos econômicos. Sobre este contexto, o presente trabalho teve por objetivo fazer um estudo hidráulico e econômico sobre a velocidade de escoamento da água em adutoras de aço galvanizado e PVC. Foi considerado uma adutora padrão, composta pela tubulação de sucção, conjunto motobomba, sistema de ligação e proteção e tubulação de recalque, operando com vazões de 50, 100, 150, 200, 250 e 300 m³ h-1 e pressões nominais de 80, 125 e 180 mca, em função do tempo de funcionamento, desnível geométrico total, custo de energia de bombeamento e de aquisição da tubulação. Verificou-se que para tubulações de aço galvanizado a velocidade econômica variou entre 0,88 e 2,65 m s-1 e para tubulações de PVC, entre 0,68 e 2,54 m s-1. Pode-se concluir que o valor da velocidade econômica é decrescente com o aumento no tempo de funcionamento da adutora e com o aumento no desnível geométrico total. A velocidade econômica foi indiretamente influenciada pelo aumento na tarifa energética e diretamente influenciada pelo aumento no custo da tubulação.Universidade Federal de Viçosa - UFV2016-03-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/53810.13083/reveng.v23i6.594Engineering in Agriculture; Vol. 23 No. 6 (2015); 503-516Revista Engenharia na Agricultura - REVENG; v. 23 n. 6 (2015); 503-5162175-68131414-398410.13083/reveng.v23i6reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/538/369Caldas, Andre Luiz DiasCarvalho, Jacinto AssunçãoRezende, Fátima Conceiçãoinfo:eu-repo/semantics/openAccess2023-01-19T13:22:54Zoai:ojs.periodicos.ufv.br:article/538Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:22:54Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false |
