Why Fluids?Why Fluids?

Brainstorm a list of engineered or biological devices that require an understanding of fluids to explain how they work.

What fluids properties do you think would be important in explaining each of the devices?

My Goals for the next six weeks...

My Goals for the next six weeks...

That each of you develop an intuition for the fundamental principles of fluid mechanics

That you leave this course saying, “Fluids makes sense” and “I can tackle fluids problems.”

That we have an enjoyable 6 weeks learning together
