The terminal velocity of a particle moving through a fluid varies as dp n. The value of n is equal to _______________ in Stoke's law regime?
Correct answer: C. 2
- A. 1
- B. 0.5
- C. 2
- D. 1.5
Explanation
In the Stokes-law regime, terminal velocity is proportional to the square of particle diameter, so vₜ ∝ dₚ² and n = 2.
