Two particles are called to be equal settling, if they are having the same ?
Correct answer: C. Terminal velocities in the same fluid & in the same field of force
- A. Size
- B. Specific gravity
- C. Terminal velocities in the same fluid & in the same field of force
- D. None of these
Explanation
Equal-settling particles are defined by having the same terminal settling velocity in the same fluid and under the same force field. They need not have the same size or specific gravity because size and density can compensate each other.
