Question 1.
What is viscous flow?
Show hintHide hint
Think about fluids like honey.
Question 2.
Define inviscid flow.
Show hintHide hint
Consider air at low speeds.
3Question 3.
What defines viscous flow?
- A flow with negligible resistance
- A flow where viscosity is significant
- A flow that is always steady
Show hintHide hint
Recap the definition we discussed.
4Question 4.
True or False: External flow occurs in a confined space.
- True
- False
Show hintHide hint
Think about how airflow interacts with an open area.
Question 5.
Design a system where you can practically observe the transition from laminar to turbulent flow. Explain how you would conduct the experiment and what indicators you would note.
Show hintHide hint
Look for changes in flow stability with increasing velocity.
Question 6.
Calculate whether airflow can be treated as incompressible or compressible at speeds approaching 200 m/s. Justify your reasoning using the Mach number.
Show hintHide hint
Consider the relationship between flow speed and sound speed in determining compressibility.
