Challenge Problems
Push your limits with advanced challenges
Analyze the momentum of a car moving through a fluid-filled tunnel. Assuming the tunnel is infinitely long, calculate the forces exerted at the inlet and outlet. What assumptions are necessary?
💡 Hint: Consider how the fluid's density and velocity affect the momentum at the boundaries.
In designing a bridge, how would you account for turbulent flow effects on momentum conservation around the bridge piers?
💡 Hint: Think about the significance of turbulence in real-world fluid behaviors.
