2 cards from this section. Quick, good the night before a test.
Define control volume in your own words.
Think about where you would apply laws of conservation in fluid mechanics.
What are body forces? Give an example.
Consider forces that act on fluids over their entire volume.
What does the conservation of momentum state?
Think about systems in equilibrium.
Which of the following forces is considered a body force?
Consider forces acting without physical contact.
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?
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?
Think about the significance of turbulence in real-world fluid behaviors.
