Syllabus: Fall 2011

Catalog Description

Engr 335 Engineering Fluid Mechanics (3 cr.). Physical properties of fluids; fluid statics; continuity, energy, momentum relationships; laminar and turbulent flow; boundary layer effects; flow in pipes, open channels, and flow around objects. Prereq: Engr 210, Math 275.

Why Study Fluid Mechanics?

To design cool products/system:

  • wind turbines, solar heating systems, jet engines, cooling of electric motors
  • rocket nozzles, reducing drag on cars, cooling of electrical components
  • flow of plastic in injection modeling, water turbines in dams, ships, heat exchangers
  • pumps, piping systems, hovercraft, hydroelectric power, cooling systems in car engines
  • fluid mechanics has millions of applications ….

Grading policies

  • A few students will get higher grades based on my professional judgement. I look especially hard @ final exam.
  • Grading system may change during semester; will provide written notification if this happens
  • After semester is over, grades are over. Happy to discuss grades anytime during semester.
  • No quiz makeups because students can miss multiple classes and still get to level 5. Special cases (e.g. illness, travel for a week, etc.) ==> I'd be happy to work with you!
