Question 904 Deck Safety

70% to pass

The difference in water spray pattern between the high-velocity tip and low-velocity applicator used with the all-purpose nozzle is due to _______________.

A the method of breaking up the water stream
B a difference in water pressure
C the length of the applicator
D All of the above
AI Explanation

The correct answer is A) the method of breaking up the water stream. The high-velocity tip and low-velocity applicator used with the all-purpose nozzle have different methods of breaking up the water stream, which results in the difference in water spray pattern. The high-velocity tip uses a more forceful, narrow stream, while the low-velocity applicator creates a wider, more dispersed spray pattern. This difference in water stream disruption is the primary factor responsible for the varying spray patterns, not differences in water pressure or applicator length.
