Question 1.
What is a strain rate tensor?
Show hintHide hint
Think about how fluids change their shape when moving.
Question 2.
Define linear strain rate.
Show hintHide hint
Consider length changes in a flowing fluid.
3Question 3.
What does the strain rate tensor measure?
- Pressure
- Deformation
- Flow Velocity
Show hintHide hint
Think about what describes changes in shape.
4Question 4.
True or False: The shear strain rate describes the increase in length.
- True
- False
Show hintHide hint
Focus on what shear implies.
Question 5.
A fluid flows through a pipe where the diameter decreases from 4m to 2m. If the initial velocity is 5 m/s, calculate the strain rates and describe how the fluid properties change.
Show hintHide hint
Consider how velocity differences across diameters impact strain.
Question 6.
In a fluid element experiencing shear strain, derive the relation between applied shear stress and shear strain rate.
Show hintHide hint
Focus on creating the relationship through experimental observations.
