2 cards from this section. Quick, good the night before a test.
What does a stress tensor represent?
Think about forces present at a point.
Define a control volume in fluid mechanics.
What space do we observe fluid behavior in?
What does RTT connect in fluid systems?
Think about what forces influence movement.
True or False: A stress tensor only includes normal stress components.
What do shear components serve to represent?
A fluid flows through a variable area duct. Define an appropriate control volume and calculate the net force acting on the fluid using RTT.
Choose entry and exit areas carefully; account for velocity changes in your integral.
Using RTT, analyze how neglecting atmospheric pressure will simplify calculations for a free discharge from a tank.
Consider how pressures balance out in all directions during discharge.
