Resumo: | The flows can be characterized as: laminar or turbulent flow; uniform or transient and compressible and incompressible. The Reynolds number is an important dimensionless quantityin fluid mechanics, that is used to help predict flow patterns in different fluid flow situationss, being defined by the ratio between inertial forces and viscous forces. The present work had as objective to use a didactic experiment of the Chemical Engineering Laboratory course, specifically Fluid Mechanics, to evoke the following concepts seen in the classroom, as well as: A) hydraulic diameter; B) Reynolds number; C) mass flow and volumetric flow; D) average flow velocity; (E) continuity equation, and visualize the different flow regimes: laminar, transition and turbulent. The experimental observation allowed a classification of the flow consistent with that of the calculations. In this experiment, it was mathematically confirmed by the uncertainty analysis and error propagation, using the EES software, the significant contribution of the water volume measurement into the values ??of the experimental errors. The effect and the contribution of temperature were also verified in the determination of the Reynolds number. |

O número de Reynolds é uma grandeza adimensional que caracteriza o movimento de fluidos, sendo definido pela razão entre forças inerciais e forças viscosas. O presente trabalho teve como objetivo utilizar um experimento didático da disciplina de Laboratório de Engenharia Química, especificamente Mecânica dos Fluidos, para evocar os seguintes estes conceitos vistos em sala de aula, bem como: a) diâmetro hidráulico; b) número de Reynolds; c) vazão mássica e vazão volumétrica; d) velocidade média do escoamento; (e) equação da continuidade, e visualizar os diferentes regimes de escoamento: laminar, transição e turbulento. A observação experimental possibilitou uma classificação do escoamento coerente com aquela dos cálculos. Neste experimento, foi confirmada, matematicamente pela análise de propagação de incertezas, usando o programa EES, a contribuição significativa da medida do volume de água nos valores dos erros experimentais. O efeito da temperatura e a contribuição de sua incerteza também foram verificados na determinação do número de Reynolds.Universidade Federal de Viçosa - UFV2017-03-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/224610.18540/jcecvl3iss3pp346-357The Journal of Engineering and Exact Sciences; Vol. 3 No. 3 (2017); 346-357The Journal of Engineering and Exact Sciences; Vol. 3 Núm. 3 (2017); 346-357The Journal of Engineering and Exact Sciences; v. 3 n. 3 (2017); 346-3572527-1075reponame:Revista de Engenharia Química e Químicainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/jcec/article/view/2246/7240Copyright (c) 2017 The Journal of Engineering and Exact Scienceshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSilva, Filipe Magalhães de CarvalhoApolinario, Mayara da FonsecaSiqueira, Antonio Marcos de OliveiraCandian, André Luiz MoreiraMoreira, Livia Andrade FontesSarti, Mateus Rodrigues2022-03-26T19:04:37Zoai:ojs.periodicos.ufv.br:article/2246Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/indexONGhttps://periodicos.ufv.br/jcec/oaijcec.journal@ufv.br||req2@ufv.br2446-94162446-9416opendoar:2022-03-26T19:04:37Revista de Engenharia Química e Química - Universidade Federal de Viçosa (UFV)false |
