Which equipment is specifically associated with gravity-fed liquid application?

• A. Gravity flow liquid applicators
• B. Boom sprayers
• C. Air blast sprayers
• D. Drone sprayers

Answer: (A)

Gravity-fed liquid application relies on gravity to move the liquid from an elevated reservoir to the spray nozzle, so no pump is required. The flow is created by the height of the liquid column and is governed by the nozzle orifice, resulting in low, steady pressure. That’s why gravity-flow liquid applicators are the ones specifically associated with gravity-fed application. Other equipment uses power to create pressure or propel droplets: boom sprayers depend on a pump to pressurize the liquid, air blast sprayers use a blower to atomize and throw droplets, and drone sprayers carry their own pumping and propulsion systems. Gravity-fed setups are simple and inexpensive, suited for small areas or situations without power, but they don’t offer the same precise pressure control as pumped systems.
