Question 1.
Define a velocity field.
Show hintHide hint
Think about how speed can vary in different places.
Question 2.
What are the components of a velocity vector?
Show hintHide hint
Remember the Cartesian coordinate system.
3Question 3.
What does a velocity field represent?
- A constant speed across all points
- Speed variation at different points
- A static fluid condition
Show hintHide hint
Think about how speed might change from one area of a fluid to another.
4Question 4.
True or False: Streamlines, pathlines, and streaklines are the same for unsteady flow.
- True
- False
Show hintHide hint
Reflect on how time changes affect flow representations.
Question 5.
A cylindrical structure is submerged in a flowing river. Discuss how you would analyze the velocity field around the cylinder using experimental and computational methods.
Show hintHide hint
Consider both physical experiments and simulation tools.
Question 6.
An airplane wing experiences different pressure gradients at various angles of attack. How would you assess the changes in velocity fields and the resultant lift?
Show hintHide hint
Think of how altering angles impacts airflow and pressure.
