3 cards from this section. Quick, good the night before a test.
Define the continuity equation.
Think about how fluid volume behaves in a flow.
What differentiates rotational flow from irrotational flow?
Consider the rotation of fluid particles.
What does the continuity equation represent in fluid flow?
Think about how mass flows when the area changes.
True or False: In irrotational flow, all components of angular velocity are zero.
Recall how angular velocities are defined.
A pipe has a diameter of 6 inches at one end and 3 inches at another. If water flows at 5 ft/s at the wider end, calculate the speed of water at the narrow end.
Use the area of a circle for A1 and A2.
