Goals:
After this class you should be able to:
- Use Bernoulli's Equation to solve for the pressure distribution in different geometries.
- Know what inviscid, irrotational flow means!
Reading
- The class notes.
- BS&L, chapter 4
Demonstration:
How blowing on a plate can actually lead to suction. While the example in class is rather whimsical, the Bernoulli effect illustrated by it is of importance in many applications. As an example, Bernoulli suction forms the basis of contactless grippers which can be used to pick up fragile objects. This is described in the Wikipedia article found here and a fun movie of such a system is found here.
