How do hollow-cone and full-cone nozzles differ in the pattern they deliver?

• A. Hollow-cone delivers most of the material to the circumference; Full-cone delivers liquid droplets to the entire area of the circle
• B. Hollow-cone delivers to the center; Full-cone delivers to the outer circle
• C. Hollow-cone delivers to the entire circle; Full-cone delivers only the edges
• D. Hollow-cone and full-cone deliver identical patterns

Answer: (A)

The pattern difference between hollow-cone and full-cone nozzles is about how the spray is distributed across the circular target area. A hollow-cone nozzle creates a ring-shaped spray, so most of the liquid is delivered to the outer edge of the circle while the center area receives little or no spray. A full-cone nozzle, on the other hand, produces a solid disc of spray that covers the entire circle, including the center, for more uniform coverage. This means the statement that matches the actual patterns is: the hollow-cone delivers most material to the circumference, while the full-cone delivers liquid droplets to the entire area of the circle. The other descriptions would imply the opposite pattern or the same pattern, which doesn’t align with how these nozzle designs distribute spray.
