Challenge Problems
Push your limits with advanced challenges
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.
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.
