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.</p>}, number={3}, journal={The Journal of Engineering and Exact Sciences}, author={Silva, Filipe Magalhães de Carvalho and Apolinario, Mayara da Fonseca and Siqueira, Antonio Marcos de Oliveira and Candian, André Luiz Moreira and Moreira, Livia Andrade Fontes and Sarti, Mateus Rodrigues}, year={2017}, month={Mar.}, pages={346–357} }
