24 Forestry- ICAR JRF/SRF 2024 MCQ (Single Correct) +4 −1 What is not an assumption of Stoke's law? A All particles have the same density Correct Incorrect B The particles are rigid, smooth ad spherical Correct Incorrect C Fluid flow around the particle is turbulent Correct Incorrect D The particles are large enough to be unaffected by the thermal motion Correct Incorrect Check Answer EXPLANATION Forest Biometrics & Experimental Designs: CRD, RBD, Latin Square, Factorial, Split-Plot & Sampling Errors 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.
