Stoke's law is valid, when the particle Reynolds number is ______________________?
Correct answer: A. < 1
- A. < 1
- B. > 1
- C. < 5
- D. None of these
Explanation
Stokes' law assumes creeping flow around the particle, for which the particle Reynolds number is less than 1. At higher Reynolds numbers, inertial effects make the Stokes drag relation inaccurate.
