mework 7 blem 11.79-Enhanced-with Hints and Feedback Determine the velocity of the particle at which Stokes' law becomes invalid, at about Re Express your answer to three significant figures and include the appropriate units Review A 2.3-mm-diameter sand particle having a density of 2.40 Mg/m3 is released from rest at the surface of oi that is contained in the tube. As the particle fails downward, "creeping flow' will be established around it. The oil has a density of p,-900 kg/m and a viscosity of Ho-30.2(10-3) N s/m2.
