Question 1.
Define volumetric strain rate in your own words.
Show hintHide hint
Think about how volume relates to fluid movement.
Question 2.
What does linear strain represent?
Show hintHide hint
Consider how objects stretch or compress.
3Question 3.
What is the definition of volumetric strain rate?
- Change in length per total length
- Change in volume per unit volume
- Force per area
Show hintHide hint
Focus on the aspect of volume rather than length or force.
4Question 4.
True or False: Shear strain rate measures the same as linear strain rate.
- True
- False
Show hintHide hint
Remember the distinctions between linear vs. shear aspects of strain.
Question 5.
A liquid flows from a large diameter pipe into a narrow pipe. Calculate the change in volumetric strain if the fluid undergoes an increase in velocity from 2 m/s to 8 m/s.
Show hintHide hint
Apply the continuity equation and conservation laws.
Question 6.
Explain how vorticity would affect volumetric strain in a turbulent flow scenario.
Show hintHide hint
Consider how fast-moving layers adjacent to slow-moving layers interact.
