Dimensionamento econômico de tubulações em sistemas de irrigação localizada.

Abstract

With the constant growth in the use of the microaspersion and trickle irrigation, it have been searched for more and more, a form of getting the minimum group eost (Distribution Net and Pumping Energy). This work presents the development of a new methodology where distinction among the calculation of the collective net and of the parcel net doesn't exist, adding the efíects of the located load losses happened in the eontrol bolsters. Two cases were calculated, the first eonsisted on the calculation of a net that had been already calculated through the methodology of the integrated optimization, and the second of a confírmation to a real example. It was observed that the obtained results were satisfactory, guaranteeing a reduction of the total costs froin 5 to 10% with relationship to the otimização methodologies that don't take into account the progresses reached on this research.
