Resumo
O presente trabalho apresenta o desenvolvimento do projeto de um sistema de irrigação para a cultura de Tyfton em uma pequena propriedade, com o objetivo de garantir o desenvolvimento da planta em questão sem que o mesmo dependa das intempéries do tempo. Antes de iniciar o projeto, em visita técnica foram levantados todos os detalhes necessários da propriedade e do terreno, contando também com auxílio do Google Earth. Foi definido o sistema de irrigação por aspersores com regulador de fluxo devido a inclinação da área e exigências da planta. Para maior eficiência no sistema de irrigação dividiu-se o sistema em 5 setores idênticos, contanto com 2 linhas de 11 aspersores cada. Calculou-se a vazão necessária multiplicando a vazão de cada aspersor pelo número de aspersores no setor chegando a necessidade de vazão de 9.900 L de água por hora. Considerando a lâmina de água exigida pela planta e a taxa de precipitação dos aspersores definiu-se o tempo de funcionamento de cada setor em 1.6 h/dia. Tendo a vazão necessária nos aspersores calculou-se todas as perdas de carga do sistema através das fórmulas de Hazen Willians, somando ao exigido pelos aspersores, definiu-se a necessidade de pressão da bomba de 79,5 mca. Considerando a perda de carga nos sistema e a vazão necessária foi analisado o catálogo e definida a motobomba que irá tocar o sistema. No AutoCAD foi desenhada a planta baixa completa de todo o projeto e os detalhamentos necessários. Por fim foi feita uma planilha com toda ficha técnica do projeto, dos cálculos hidráulicos realizados e das especificações do motobomba escolhida.
The present work presents the development of the project of an irrigation system for the Tyfton crop in a small property, with the objective of guaranteeing the development of the plant in question without it depending on the weather. Before starting the project, during a technical visit, all the necessary details of the property and land were surveyed, also relying on the help of Google Earth. The sprinkler irrigation system with flow regulator was defined due to the slope of the area and plant requirements. For greater efficiency in the irrigation system, the system was divided into 5 identical sectors, with 2 lines of 11 sprinklers each. The necessary flow was calculated by multiplying the flow of each sprinkler by the number of sprinklers in the sector, reaching the need for a flow of 9,900 L of water per hour. Considering the water depth required by the plant and the sprinkler precipitation rate, the operating time of each sector was defined as 1.6 h/day. Having the necessary flow in the sprinklers, all the head losses of the system were calculated through the Hazen Williams formulas, adding to the required by the sprinklers, the need for pump pressure of 79.5 mca was defined. Considering the pressure drop in the system and the necessary flow, the catalog was analyzed and the motor pump that will touch the system was defined. In AutoCAD, the complete floor plan of the entire project and the necessary details were drawn. Finally, a spreadsheet was made with all the technical details of the project, the hydraulic calculations carried out and the specifications of the chosen motor pump. Keywords: tyfton, irrigation, sprinkler, motopump.
