Question Statement:
An air induction (venturi) spray nozzle reduces drift by:
Options:
(A) Drawing air into the fluid passage through venturi holes, producing large air-cushioned droplets that do not drift readily
(B) Reducing fluid velocity to zero
(C) Heating the spray solution
(D) Filtering out active ingredient
Answer Key:
A
Step-by-Step Solution & Explanation
Air induction nozzles mix air into spray droplets; the larger droplets resist wind drift and shatter upon leaf impact.
