Equivalent diameter of particle relative to sphere is the diameter of sphere who's volume same as particle volume.

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.

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.

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.
