2 cards from this section. Quick, good the night before a test.
Define velocity field in the context of fluid mechanics.
Focus on how velocity varies across positions.
What is a streamline?
Think about its relation to fluid flow direction.
What does a velocity field represent in fluid mechanics?
Think about the vector nature of this concept.
True or False: Streamlines can intersect in a fluid flow.
Consider what would happen if this were allowed.
Given a scenario where fluid velocity increases sharply past an object, analyze the potential impact on pressure and discuss the implications.
Consider Bernoulli's equation and pressure relationships.
Visualize a complex flow around varying geometries. Discuss how streamlines, pathlines, and streaklines would appear and behave.
Use examples to illustrate each line’s behavior.
