Office Hours? Homework due

Why Fluids? ä Brainstorm a list of engineered or biological devices that require an understanding of fluids to explain how they work. ä What fluids properties do you think would be important in explaining each of the devices? ä Brainstorm a list of engineered or biological devices that require an understanding of fluids to explain how they work. ä What fluids properties do you think would be important in explaining each of the devices?

Course Topics ä Pipe Flow ä How big does the tunnel have to be that carries drinking water into NYC? ä External Flows ä How much power does it take to drive a new VW beetle at 100 kph? ä Open Channel Flow ä How deep will the water be in Fall Creek during a spring snow melt caused by a warm rain? ä Pipe Flow ä How big does the tunnel have to be that carries drinking water into NYC? ä External Flows ä How much power does it take to drive a new VW beetle at 100 kph? ä Open Channel Flow ä How deep will the water be in Fall Creek during a spring snow melt caused by a warm rain?

My Goals for the next six weeks... ä That each of you develop an intuition for the fundamental principles of fluid mechanics ä That you leave this course saying, “Fluids makes sense” and “I can tackle fluids problems.” ä That we have an enjoyable 6 weeks learning together ä That each of you develop an intuition for the fundamental principles of fluid mechanics ä That you leave this course saying, “Fluids makes sense” and “I can tackle fluids problems.” ä That we have an enjoyable 6 weeks learning together
