Question 1
What is a path line?
- The trajectory of all fluid particles
- The path of an individual fluid particle
- The average direction of fluid flow
💡 Hint: Look for the individual perspective.
Question 2
True or False: Stagnation points have a fluid velocity greater than zero.
- True
- False
💡 Hint: Think of where the flow stops.

Challenge Problems
Push your limits with challenges.
Question 1
A water flow visualization experiment shows that a dye, injected into a water pipe, forms distinct streak lines. Calculate the positions of two streak lines as the flow rate changes, indicating particle movement.
💡 Hint: Focus on how the velocity impacts the spread of the dye.
Question 2
Discuss the implications of stagnation points at various shapes of objects in fluid flow. How does the angle or shape affect the pressure exerted at the stagnation point?
💡 Hint: Think about how cars are designed to minimize drag and optimize flow.
