Question

In the Tayler standard screen scale series, when the mesh number increases from \(3\) mesh to \(10\) mesh, then the

• A. Clear opening decreases
• B. Clear opening increases
• C. Clear opening is unchanged
• D. Wire diameter increases

Hint:

Higher mesh number means finer screen and smaller clear opening.

Answer 1

The Correct Option is A

Mesh number represents the number of openings per linear inch of a screen. If mesh number increases, the number of openings per inch increases. This means each opening becomes smaller. So, as mesh number increases from \(3\) mesh to \(10\) mesh, the screen becomes finer. A finer screen has smaller clear opening. Therefore: \[ \text{mesh number increases} \Rightarrow \text{clear opening decreases} \] Thus, the correct answer is: \[ \text{Clear opening decreases} \]
