Practical and Simple Laboratory Experiment to Visualize the Correlation among the Hydraulic Flow Parameters in Pipes.

The article presents the development and execution of a simple practical experience, which aims to help students of a civil engineering course, in a better understanding of the theoretical concepts involved in the topic of head loss in pressurized hydraulic conduits. Initially, a literature review is carried out, regarding the importance of practical classes in student training, laboratory practices, and experiments. Afterwards, the methodology used is presented, through measurement tests and the respective impacts on the flow rate, obtained by varying, one at a time, the length of the pipe, its diameters, and height between the water level in the reservoir and the water outlet point. The flow values varied as initially assumed. Finally, through the Fair-Whipple-Hsiao formula for small diameter plastic tubes, calculated flow values were obtained for each of the situations, and contrasted with the respective measured values. The results were considered satisfactory. [ABSTRACT FROM AUTHOR]
