3 cards from this section. Quick, good the night before a test.
What is the conservation of mass?
Think about how mass behaves in a flowing system.
Write the definition of shear strain rate.
Consider how fluids change shape under stress.
What does the continuity equation ensure?
Think about how water enters and exits a pipe.
True or False: The shear strain rate only refers to changes in fluid volume.
Recall the distinction between form change and size change.
In a pipeline, the diameter is reduced from 2 meters to 1 meters. If the velocity of water at the larger diameter is 3 m/s, what is the velocity at the smaller diameter? Use the continuity equation.
Recall area formulas for circles and how they relate to diameter.
Explain how assumptions of fluid incompressibility simplify hydraulic analysis, and provide an example of where this might not hold true.
Think about how changes in temperature and pressure affect gas behavior.
