What is not an assumption of Stoke's law?
EXPLANATION
Forest Biometrics & Experimental Designs
- Stokes' Law Assumptions in Sedimentation:
- Particles are rigid, smooth, and spherical.
- Particles share uniform density (typically $2.65\text{ g/cm}^3$).
- Particles are large enough ($\gt 0.2\ \mu\text{m}$) to be unaffected by Brownian thermal motion.
- Fluid flow around the falling particle is strictly laminar ($Reynolds\ number \lt 0.1$).
- Incorrect Assumption: Assuming turbulent flow is directly contradictory to Stokes' Law derivation. (Correct answer: Option 3)
