Course Objectives

1. Understand the physics of the molecular transport processes and the rate laws; understand and know how to exploit the analogies between the diffusive transport phenomena of viscous flow, heat conduction and species diffusion.
2. Understand the construction and use of shell balances for setting up and solving transport problems, particularly those involving viscous flow.
3. Understand the origin and use of the Navier-Stokes equations and their simplification to specific flow situations.
4. Understand the concepts of turbulence, friction and drag and their application to flow in conduits, packed beds and around submerged objects.
5. Understand the application of mechanical energy balances (Bernoulli analysis) to practical piping, pumping and flow problems.
