Air Velocities Delivered by Orchard Air Sprayers

REGRESSION equations were developed to show the effect of travel speeds and of horizontal and vertical distances from the outlet on the air velocity delivered by three types of orchard air sprayers. The regression equa-tions show the rate that air velocities produced by orchard air sprayers decrease as travel speed increases and how rapidly velocities diminish with increasing dis-tance from the outlet. Air velocity decreased at lesser rates for sprayers delivering greater air mass flows. The sprayer jets conform fairly well to the basic structure of idealized jets.
