What term describes a mixing method in which some solution circulates through the pump and back into the tank?

• A. Hydraulic agitation
• B. Mechanical stirring
• C. Aeration
• D. Ultrasonic mixing

Answer: (A)

Hydraulic agitation describes circulating some of the tank mix through the pump and back into the tank. In this setup, a portion of the liquid is drawn from the tank, pumped through the system, and returned, creating continuous flow that keeps the entire mixture in motion. This keeps solids from settling and maintains a uniform distribution of the active ingredient and additives during spraying. It’s different from mechanical stirring (uses an internal paddle or stirrer), aeration (adds air bubbles), or ultrasonic mixing (uses high-frequency vibrations).
