✦ Synopsis
E!ectiveness of hydraulic jet agitation systems of agrochemical sprayers was investigated by measuring the concentration of a kaolin clay/water mixture in the line to the boom. Experiments were conducted on several sprayer tanks of di!erent capacities and agitator types. An initial series of tests identi"ed the most important parameters a!ecting the e$ciency of a particular agitation system. An experimental design was chosen to determine the e!ect of each parameter as well as interactions among them. An agitation index was used to evaluate the e!ectiveness of each agitation system separately, regardless of tank size and shape. Statistical analysis of agitation e!ectiveness (AGEF) values showed that the system pressure was the most important factor a!ecting agitation e!ectiveness through its direct in#uence on jet velocity. If the jet velocity was kept constant, then the volume of #uid delivered into the tank was the most important factor in enhancing mixture uniformity.
