Question 1

What is the conservation of momentum?

  • Momentum changes with time
  • Momentum remains constant in a closed system
  • Momentum always increases

💡 Hint: Consider how momentum behaves in a closed system.

Question 2

True or False: Momentum flux correction factors are used only for uniform flow conditions.

  • True
  • False

💡 Hint: Think about when flow conditions are complex or vary significantly.

Challenge Problems

Push your limits with challenges.

Question 1

For a pipe with a flow section experiencing varying velocities, derive the momentum flux using correction factors and illustrate how this impacts the overall system.

💡 Hint: Utilize real experimental data to better understand how these corrections affect the calculations.

Question 2

Consider a scenario of turbulent flow around bridge piers. Formulate the momentum equations reflecting the forces acting on the piers and resulting fluid behavior.

💡 Hint: Visual aids can help represent varying pressure landscapes effectively.
