Avaliação de um injetor venturi funcionando para aeração de água.

Abstract

This study was conducted of the Hydraulic Laboratory of University of São Paulo, Piracicaba, Brazil, to determine the performance of injector type Venturi conected in irrigation pipe lines to inject air into the body water for the distribution of oxygen. The injectors were tested by supply pressure of 49,0 to 269,5 kPa, with increment of 24.5 kPa. It was studied variables as: injector head losses; injector discharge suction of air in ten operation pressure and variables flows rates. The major efficiency obtained was 9.58 %. The obtained results permit to establish clarifying tecnical knowledge about the performance on such devices and making possible an appropate choice to their different applications.
