3 cards from this section. Quick, good the night before a test.
What is a control volume in fluid mechanics?
Think about the area we analyze.
How many components are there in a stress tensor?
Relate it to normal and shear stresses.
What are stress tensors primarily used for?
Think about how forces are represented.
True or False: Body forces only act at the surface of a fluid.
Consider the force's distribution.
Calculate the total pressure force and gravity force acting on a subset control volume from a fluid at rest.
Use both surface and volume integrals.
Given a fluid flow situation, define an appropriate control volume and justify your design choice.
Reference how pressure distributions might cancel.
