but also improves the uniformity of the spray pattern. Turbulence chamber nozzles are available in a turbo flood tip and now in the turbo flat-fan design. The turbo flatfan design shows great improvements in pattern uniformity when compared to the extended range flat-fan and other drift reduction flat-fan designs. In addition, the turbo flat-fan has significantly reduced the percentage of drift...
متن کاملMethodology for the Regulation of Boom Sprayers Operating in Circular Trajectories
A methodology for the regulation of boom sprayers working in circular trajectories has been developed. In this type of trajectory, the areas of the plots of land treated by the outer nozzles of the boom are treated at reduced rates, and those treated by the inner nozzles are treated in excess. The goal of this study was to establish the methodology to determine the flow of the individual nozzle...
متن کاملCharacteristics of Hydraulic Jump
The effect of an abruptly expanding channel on the main characteristics of hydraulic jump is considered experimentally. The present study was made for supercritical flow of Froude number varying between 2 to 9 and approach to expanded channel width ratios 0.4, 0.5, 0.6 and 0.8. Physical explanations of the variation of these characteristics under varying flow conditions are discussed based on t...
متن کاملevaluate and develop new relationships to estimate submerged hydraulic jump characteristics
in this research, in order to develop new relationships with reasonable accuracy for estimation of the submerged hydraulic jump characteristics, a study has been conducted experimentally. experiments have been done in a rectangular channel with a length of 9 m, a width of 0.5 m and a depth of 0.45 m. froude numbers in these tests range from 3.5 to 11.5 and between submergence ratios of 0.1 t...

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
