7. 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?

10. 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
