Question 1.
Define viscosity.
Show hintHide hint
Think of what makes some fluids thicker than others.
Question 2.
What does the no-slip condition refer to?
Show hintHide hint
Consider how fluids behave when in contact with surfaces.
3Question 3.
What is viscosity?
- A measure of temperature
- Resistance to flow
- Mass of a fluid
Show hintHide hint
Think about thick vs. thin fluids.
4Question 4.
True or False: The no-slip condition means fluid travels with the same speed as the surface.
- True
- False
Show hintHide hint
Visualize a fluid layer sticking to a surface.
Question 5.
If a fluid has a viscosity of 0.75 Pa.s and a shear rate of 30 s^-1, calculate the shear stress.
Show hintHide hint
Remember the formula relating viscosity to shear stress and shear rate.
Question 6.
Discuss how viscosity changes with temperature, providing both theoretical background and practical examples.
Show hintHide hint
Think about how heating affects fluid properties in a kitchen.
