Subtopic: Cost analysis of implements and tractors
Question Statement:
The type of typical spray distribution profile of a hollow cone nozzle is
Options:
(A) steep sided slopes
(B) gradual sloping sides
(C) narrow topped with gradual slopes
(D) narrow topped with steep sides
Official Answer Key:
A
Step-by-Step Solution & Explanation
A hollow-cone nozzle produces spray that is concentrated in a ring/cone shell (little liquid at the very centre of the pattern), so the cross-sectional distribution profile rises sharply from near-zero at the centre and falls sharply at the pattern edge — i.e., a profile with steep sided slopes, in contrast to a flat-fan nozzle's more gradual, tapering triangular profile. Answer: (A).
