Reciprocal of sphericity is termed as the________________?
Correct answer: B. Shape factor
- A. Specific surface ratio
- B. Shape factor
- C. Sauter diameter
- D. Surface area per unit mass
Explanation
Sphericity compares the surface area of a volume-equivalent sphere with the actual particle surface area, so its reciprocal is a shape factor. The other options describe surface-area measures or a particle-size diameter.
