4 cards from this section. Quick, good the night before a test.
Define the continuity equation in your own words.
Think about how changes in area affect flow.
What is rotational flow?
Consider the angular momentum of the fluid particles.
What does the continuity equation represent in fluid dynamics?
Think about what happens to mass in flowing fluids.
True or False: Irrotational flow means vorticity is present.
Consider what defines rotational behavior.
A cylindrical tank is filled with water and has a pipe at the bottom with an area of 0.005 m². If the water height is 2m, calculate the velocity of water exiting the pipe.
Use conservation of mass and consider gravitational effects.
Given a flow field described by the stream function ψ = x² - y², find the velocity components and assess whether the flow is rotational or irrotational.
Focus on partial derivatives and connections to vorticity.
