Estudo comparativo entre metodologias de dimensionamento de adutoras

Abstract

The method used in the design of a penstock is directly related to the results that will be obtained, considering that each mathematical model takes into account different factors, as they are proposed from different analyses. Therefore, the present thesis intends to understand how the application of the Darcy – Weisbach and Hazen – Williams equations influences in the obtainment of head loss in a penstock, as well as to evaluate the main differences between the Bresse equation and the continuity equation with a fixed maximum speed. For both analyses, a water main in the municipality of Paraná State City in northern Paraná was studied, which was visited and consulted the planks of your executive project. The results obtained showed how the different methods lead to different values, and also showed how the different models lead to different difficulties in the elaboration and solution of the problem. Another analysis made was an opinion poll that sought to understand which mathematical methods teachers and engineers who work with sizing of water mains prefer to use to calculate the head loss and diameter of a pipeline, as well as the reason for this choice. The results of this survey showed how professionals from different areas solve the same problem differently because they have different priorities.
