3 cards from this section. Quick, good the night before a test.
What does the Reynolds number indicate?
Think about what factors affect fluid flow.
Define shear stress.
Consider how forces are distributed across surfaces.
What does a high Reynolds number indicate?
Think about the flow type associated with high velocities.
Dynamic similarity ensures what?
Consider the conditions needed for model testing.
Calculate the Reynolds number for a fluid with density 1000 kg/m³ flowing at a velocity of 2 m/s through a pipe of diameter 0.1 m and dynamic viscosity of 0.001 Pa.s.
Use the Reynolds number formula to relate the terms.
Discuss how the principles of fluid mechanics can be applied to predict the economic growth of a city. Provide examples.
Think about how fluid dynamics can represent flow in different contexts.
