Sphericity for a non-spherical particle is given by (where, V and S are volume and surface area respectively of one particle. and, D = equivalent diameter of particle)?
Correct answer: A. 6.V/D.S
- A. 6.V/D.S
- B. V/6D.S
- C. D.S/V
- D. V/D.S
Explanation
Sphericity is the surface area of a sphere having the same volume divided by the actual particle surface area. With equivalent diameter D, the equal-volume sphere area is 6V/D, giving φ = 6V/(DS).
