Question 1.
What is the divergence of velocity?
Show hintHide hint
Think about fluid spreading out.
Question 2.
Name one common Newtonian fluid.
Show hintHide hint
Consider fluids with constant viscosity.
3Question 3.
What does the divergence of velocity indicate?
- The speed of fluid
- The net volume outflow
- The pressure of fluid
Show hintHide hint
Remember, it's about fluid departure.
4Question 4.
True or False: Non-Newtonian fluids exhibit constant viscosity.
- True
- False
Show hintHide hint
Consider how they react under stress.
Question 5.
A tank holds water. If the flow rate of water entering the tank is greater than the flow rate of water exiting, how will you describe the divergence of velocity in this situation?
Show hintHide hint
Consider your inflow vs. outflow rates.
Question 6.
Given a non-Newtonian fluid, describe how its behavior changes if subjected to increasing shear stress. What implications does this have for divergence?
Show hintHide hint
Think about how stress affects fluid consistency and flow.
