In Newton's law range, the drag co-efficient for the motion of spherical particle in a stationary fluid is___________________?
Correct answer: A. 0.44
- A. 0.44
- B. 0.044
- C. 4.4
- D. 44
Explanation
In the Newton or high-Reynolds-number range, the drag coefficient of a smooth spherical particle is approximately 0.44. The other values differ by factors of 10 or 100 and are not the standard sphere value.
