For the sedimentation of a suspension of uniform particles in a liquid, the relation between observed sedimentation velocity Up and fractional volumetric concentration C is given by Up = UTɛ 4.8 where UT is the free-falling velocity of an individual particle. Calculate the concentration at which the rate of deposition of particles per unit area will be a maximum, and determine this maximum flux for 0.15 mm spheres of glass (density 2500 kg/m3 ) settling in water (density 1000 kg/m3 , viscosity 1 mNs/m2 ). It may be assumed that the resistance force F on an isolated sphere is given by Stokes’ law.

Discuss how teen subcultures are diverse. Discuss the impact of teen subcultures on valuing diversity. In what ways do teen subcultures bond diverse people together (athletes of different races, for example) and help them to understand one another better? In what ways do teen subcultures separate people into “cliques” or foster stereotyping (“us” vs. “them”)?
Based on this exercise, what are the challenges for organizations that are seriously attempting to value diversity? What are the benefits to these organizations? How do organizations train people about cultural (and subcultural) differences without falling into stereotyping?
