In the experiments, the nozzle diameters were varied as 26, 33 and 38 mm. In addition, the distances from throat to nozzle (0.5, 1, 1.5 and 2.0 cm) were studied to gain the most air volume passing thru the aerator. The highest air velocity was detected when the 26 mm nozzle diameter was used and the suitable distance from throat to nozzle was 1.0 cm. Find Abstract
