Question:
Which of the following screens are numbered according to the number of opening per inch in each direction?
Which of the following screens are numbered according to the number of opening per inch in each direction?
Show Hint
As the mesh number increases, the opening size of the screen decreases.
A 200-mesh screen has much smaller openings (\(0.074\text{ mm}\)) than a 10-mesh screen (\(2.0\text{ mm}\)).

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Sieves and screens are industrial devices used to separate particles based on size.
Standard specifications are used to designate the size and frequency of the openings.
Step 2: Detailed Explanation:
- Wire mesh screens (woven wire sieves) are designated by their "mesh number."
- The mesh number is defined as the number of openings per linear inch (\(25.4\text{ mm}\)) of the screen, counted in each direction from the center of any wire.
- For example, a 100-mesh screen has 100 openings per linear inch.
- Perforated plates are specified by the physical diameter of their holes rather than mesh counts.
Step 3: Final Answer:
The correct screen type is the Wire mesh, which corresponds to option (C).
