Three, twenty-minute, in-class quizzes will be given. The top two quiz scores will be counted toward your grade. The midterm exam will last one class period. The final exam will be comprehensive. Discuss any potential conflicts well before the exam dates. There will be no make-up quizzes or exams.

Students are expected to turn in laboratory assignment and homework problems that are substantially the result of their own work. Study groups, discussion of assignments among students, collective brainstorming for solutions, and sharing of advice is encouraged. Copying of assignments, computer files, graphs, or other means of duplicating material that is turned in for grading is expressly forbidden. Cheating on exams will result in a zero grade for the exam.

On-line animations of simple fluid flow are available on this page.
Wind tunnels are used for experiments in external flow, i.e. flows in which an object is emmersed in a larger body of moving fluid. For years the fluids engineering division of NASA Ames Laboratory was home to the largest wind tunnel in the world. Alas, the 80 x 120 has been decommisioned along with the 12 foot pressurized wind tunnel. This leaves the relative new 40 x 80 low speed tunnel, the 11 foot transonic tunnel, and the 9 x 7 foot supersonic wind tunnel as the large wind tunnel facilities at Ames. The European Transonic Wind Tunnel is another example of a large wind tunnel.
Oregonians (and visitors) interested in flight will want to visit the Evergreen Aviation Museum and the Tillamook Air Museum. Here are some photos I took on a trip to the Evergreen Air Museum. You will also want to visit the Museum of Flight on your next trip to Seattle.
If you are interested in marine travel be sure to visit the Columbia River Maritime Museum.
The Pitch Drop Experiment at the University of Queensland in Austrailia shows how something that appears to be solid can flow. Also see the article from the European Journal of Physics that describes models of viscosity for the pitch. Is pitch a Newtonian fluid?
