Equivalent diameter of a particle is the diameter of the sphere having the same

 [A]. ratio of surface to volume as the actual volume. [B]. ratio of volume to surface as the particle. [C]. volume as the particle. [D]. none of these.

Explanation:

No answer description available for this question.

 Transparently said: (Aug 27, 2016) Equivalent diameter of particle relative to sphere is the diameter of sphere who's volume same as particle volume.

 Raja said: (Jan 4, 2017) I think Option C is correct.

 Swaraj said: (Apr 12, 2017) Yes, you are correct @Raja.

 Kirilov said: (Apr 18, 2017) D is correct as the definition of equivalent diameter is "Size of a spherical particle having the same controlling characteristic as the particle under consideration". In the given question, there is no controlling character mentioned.

 Satya said: (Aug 13, 2017) A) is the correct answer.

 Abhijeet said: (Sep 25, 2017) How?

 Chemico said: (Dec 6, 2017) It comes from sphericity. The diameter used in sphericity is called the equivalent diameter.

 Devarsh Parikh said: (Oct 21, 2018) I think the answer is C. Because we always take the diameter of the sphere which has same volume as the particle for the calculation.

 Rahul Maurya said: (Sep 15, 2019) Yes, A is correct. Agree with the given answer.

 Nandini said: (Nov 16, 2020) Answer C is right. Because equivalent diameter is defined as the diameter of sphere of equal volume as that of the particle, which is used in finding the sphericity of a particle.

 Roshni said: (Jan 10, 2021) Option C is correct because we consider a sphere of same volume of the irregular particle.

 Nisanth Jena said: (Feb 23, 2021) A is correct as it's the definition of sphericity.
