Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What is the momentum conservation principle?

  • It states that momentum can change over time
  • The total momentum remains constant in a closed system
  • Momentum is lost during fluid flow

💡 Hint: Think of systems like closed containers.

Question 2

Reynolds Transport Theorem relates what two aspects?

  • True
  • False

💡 Hint: Consider how we analyze flows in and out of control volumes.

Challenge Problems

Push your limits with challenges.

Question 1

A water jet exits a nozzle with an internal diameter of 0.05m and a velocity of 10 m/s. Calculate the momentum flux and compare it to that of a jet with a diameter of 0.1m and a velocity of 5 m/s.

💡 Hint: Use A = π(d/2)^2 for area calculation.

Question 2

Describe how the variation in pressure along a bridge pier affected by a flowing river can change the structural design of the pier. What calculations would be necessary?

💡 Hint: Consider using CFD simulations to visualize these forces.
