For raschig rings, the sphericity is_____________________?
Correct answer: C. < 1
- A. 0.5
- B. 1
- C. < 1
- D. √3
Explanation
Sphericity equals the surface area of an equal-volume sphere divided by the actual particle surface area, and it is 1 only for a sphere. A Raschig ring is non-spherical, so its sphericity is less than 1.
