Question 140General Subjects - 1st Asst/Chief70% to pass
Which of the following statements best describes the filtering ability of a fine mesh metal lube oil strainer?
AI Explanation
The correct answer is D) A 200 wire mesh screen will prevent passage of smaller particles than a 100 wire mesh screen.
The reasoning is that a higher wire mesh number (200) indicates a finer filtration, with smaller openings between the wires compared to a lower wire mesh number (100). This means the 200 mesh screen will capture and prevent the passage of smaller particles than the 100 mesh screen.
The other options are incorrect because:
A) Both screens do not necessarily allow the same size particles to pass, as the 200 mesh screen filters out smaller particles.
B) The statement in B is incorrect, as the 200 mesh screen, not the 100 mesh screen, prevents passage of smaller particles.
C) The statement in C is incorrect, as a higher wire mesh number (200) indicates smaller wire size, not larger.
