Drag co-efficient for motion of spherical particles in a stationary fluid in the stoke's law range is_________________?
Correct answer: A. 24/NRe,P
- A. 24/NRe,P
- B. 16/NRe,P
- C. 64/NRe,P
- D. 48/NRe,P
Explanation
For spherical particles in the Stokes-law range, the drag coefficient varies inversely with particle Reynolds number and is given by C_D = 24/Re,p. This relation applies when Re,p is very small, typically below about 1.
