Sistemas hidráulicos prediais: Um novo método de dimensionamento

Abstract

Hydraulic systems are responsible for conducting water from a point of supply to the points of use, ensuring comfort, hygiene, safety and economy for building users. However, because they are closely related to the transport of a fluid in a turbulent flow regime, the theories and, especially, the equation used must be in accordance with the characteristics and descriptions of such a physical phenomenon. In this work, we sought to analyze the current theoretical knowledge base, through a detailed study - including historical - of the nationally employed equation, seeking, mainly, a qualitative improvement of the currently proposed normative parameters; allied to an experimental study, necessary to complement and/or prove, in an empirical way, the theoretical knowledge. In this way, by seeking an improvement in current normative parameters, it was possible to achieve the objective of this work to seek a reduction in the cost of implementing these systems, and to improve both the performance and the reliability of the designer to the same, which, in turn, passes, through the sizing method proposed in this work, to have greater control over the particularities of each system, including visualizing the critical parameter in its design. In addition to enabling a reduction in the cost of previously designed systems, the studies developed in this work have succeeded in initiating a new line of research into fluid mechanics, since it was possible to observe a variation in the dimensionless coefficient of the connection, as other adjacent connections are installed nearby. Although, in the beginning, the analysis of building systems has been focused, there is nothing to prevent the use of the proposed design method in other systems, such as: industrial systems, water mains (raw/treated), among others.
