Question 1.
What happens when a shear force is applied to a solid?
Show hintHide hint
Think about what solids do under pressure.
Question 2.
Define the no-slip condition in your own words.
Show hintHide hint
Consider what happens at the boundary layer.
3Question 3.
What characterizes fluids under shear stress?
- They do not deform
- They continuously deform
- They return to original shape
Show hintHide hint
Think about the properties of liquids.
4Question 4.
True or False: In the no-slip condition, fluid particles in contact with a solid surface have velocity equal to zero.
- True
- False
Show hintHide hint
Remember the definition of no-slip condition.
Question 5.
You have a tank filled with water and a submerged object. Explain how the no-slip condition affects the flow of water around the object and what design implications this has for creating hydrodynamic shapes.
Show hintHide hint
Consider how forces act on the submerged object.
Question 6.
Analyze a scenario where a fluid behaves unexpectedly due to violating the assumptions of incompressibility. Discuss the implications in an engineering design context.
Show hintHide hint
Reflect on how pressure changes affect flow continuity.
