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.

A) is the correct answer.

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.
