1. Objective- Appreciate the settling phenomenon of round-shape solid objects caused by gravity.- Understand the concept of fluid viscosity and its effects on the sedimentation of the objects.- Determine the values of drag coefficient C0 and Reynolds Number as well as understand the relationship between these dimensionless parameters.- Examine the Stokes’ law: its limitation and application.2. TheorySedimentation is the settling of a particle, or suspension of particles, in a fluid due to the effect of an external force such as gravity, centrifugal force or any other body force.
