5 cards from this section. Quick, good the night before a test.
What is a velocity gradient?
Think about how speed varies in different layers of fluid.
What does angular velocity measure?
Consider it like spinning around an axis.
What does a velocity gradient indicate?
Focus on the relationship between velocity and distance.
True or False: Vorticity measures the local rotation of fluid.
Consider the movement of fluid particles.
A fluid element is flowing through a pipe with a diameter change from 2 m to 1 m. Calculate the linear and shear strains experienced by the element.
Use the principles of conservation of volume and understand flow behavior.
Given a vorticity of 0.5 s^-1 how would you find the angular velocity associated with this vorticity?
Remember the relation between vorticity and angular movement.
