Show hintHide hint
Think about how length changes with respect to the initial length.
Question 2.
What does it mean if the linear strain is positive?
Show hintHide hint
Consider how fluid elements behave when experiencing stress.
3Question 3.
What is the linear strain rate?
- Rate of deformation per unit length

- True
- False
Show hintHide hint
Consider scenarios where fluid density might change.
Question 5.
A fluid flows from a pipe of diameter 0.5 m into another of diameter 1.0 m. Calculate the expected linear strain and describe the physical implications.
Show hintHide hint
Understand the geometry of flow and the basic principles of continuity.
