2 cards from this section. Quick, good the night before a test.
What is hydrostatic pressure?
Think about fluids that are not moving.
Define the term shear stress (τ_ij).
Focus on how fluids resist deformation.
What does the Navier–Stokes equation govern?
Think about where you see fluids moving.
Hydrostatic pressure increases with depth in a fluid.
Consider how liquids behave under pressure.
Derive the relationship between shear stress and shear strain rate in a Newtonian fluid.
Remember the definition of viscosity.
Given a fluid with a known density, calculate how pressure varies with depth in a column 10m deep?
Keep in mind the standard gravity constant.
