Dimensionamento de sistema de irrigação por pivô central em plano inclinado

Abstract

Center pivots stand out as a crucial solution in agricultural practices, providing a valuable alternative to mitigate the vulnerability of rural workers in the face of unpredictable rainfall and the climatic effects of drought. Efficiency in the use of water and energy over long distances is the main advantage of this system, making precise sizing and the appropriate choice of equipment essential according to water demand and local conditions. As a result, there is a need to develop mathematical models to guide decisions when implementing the project. This work proposes the creation of an algorithm using EES (Engineering Equation Solver) software to apply fundamental concepts such as flow machines, flows, head loss and mass balance, taking into account the specific factors of the chosen location. The results obtained from the algorithm are analyzed and presented graphically, exploring the physics underlying the system's behavior. In addition, the study includes a comparison of energy consumption between the scenario with and without the frequency inverter, providing valuable insights for a more efficient and sustainable operation of the center pivot.
