Challenge Problems
Push your limits with advanced challenges
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?
💡 Hint: 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.
💡 Hint: Think of how you can simplify this by focusing on small parts rather than treating the entire volume at once.
