3 cards from this section. Quick, good the night before a test.
Define steady flow.
Think about how things would remain unchanged in the flow.
What does incompressible flow imply?
Consider fluids like water.
What is a characteristic of steady flow?
Recall the definition of steady.
True or False: In an incompressible flow, the density of fluid changes.
Think about which fluids can be considered incompressible.
You have a water pipe system with an inlet having a diameter of 5 cm and an outlet of 3 cm. Given the flow is steady and incompressible, how does the velocity change as it moves through the pipe?
Remember: Area increases with area decreases for an incompressible fluid.
Analyze a scenario where the control volume is deformable while discussing how you would manage integrating velocity changes over time.
Think of how you can simplify this by focusing on small parts rather than treating the entire volume at once.
