Which statement about LF and nozzle wear is correct?

• A. LF seldom clogs nozzles.
• B. LF clogs nozzles frequently.
• C. LF has no effect on nozzle wear.
• D. LF corrodes nozzle materials rapidly.

Answer: (D)

The main concept here is that the chemical makeup of a liquid sprayed through a nozzle can attack and wear the nozzle material. Some LF formulations contain solvents or acidic components that corrode metal and certain plastics used in nozzles. This corrosion removes material from the nozzle, increases roughness at the orifice, and changes the flow path, which quickly degrades spray performance and shortens nozzle life. That’s why the statement about LF corroding nozzle materials rapidly is the best answer: it reflects the real mechanism by which these liquids damage nozzle components. While clogging can happen with some formulations, and residue can form in nozzles, the primary concern with corrosive liquids is wear from material loss and surface attack. Saying LF has no effect on nozzle wear is inaccurate, and claiming it only clogs nozzles doesn’t capture the main risk.
