5 cards from this section. Quick, good the night before a test.
What is gauge pressure?
Think about how you measure pressure in everyday items.
List two components of the stress tensor.
Consider the forces acting on fluid surfaces.
What is the primary consideration when defining gauge pressure?
Think about how you would measure pressure around us.
True or False: Shear stress occurs perpendicular to the surface.
Consider how forces act on a surface.
Given a fluid with a known shear stress and pressure gradient, derive the total stress tensor in a control volume.
Focus on combining the shear and normal stress equations into a tensor format.
In a hydraulic system operating at varying atmospheric pressures, discuss how control volumes would be defined to isolate the internal fluid pressures.
Consider how changes in external conditions demand adjustments in the definitions of your control volume.
