Aspersão convencional: simulações de dimensionamento econômico em planilha eletrônica.

Abstract

The design of a sprinkler hand-move system based on an economic analysis, allow diameters can be used in differents situations, supplying project options not only more economics but also convenient. The present paper analyze differents operations situations of a sprinkler portable system, through eletronic spreadsheet (Excel 5.0), searching the best combination in terms of total cost by hectare. According to the values obtained in differents combinations, of principal line (4,5,6, 8 “) and lateral line (2,3, 4”) its possible to select the best alternative. It was observed that the most economic combination of diameters, was 6 inches for the principal line and 4 inches for the lateral line.
