Question 1.
Define the term 'stream function'.
Show hintHide hint
Think about what it represents in the flow.
Question 2.
What does the conservation of mass imply?
Show hintHide hint
It relates to fluid flow continuity.
3Question 3.
What is the significance of the stream function?
- It reduces the number of dependent variables in fluid analysis.
- It increases system complexity.
- It is irrelevant in fluid mechanics.
Show hintHide hint
Think about what function aids in simplifying equations.
4Question 4.
True or False: Body forces act only at the fluid's surface.
- True
- False
Show hintHide hint
Recall the definitions of each type of force.
Question 5.
Derive the mathematical expression for mass flow rate in terms of the stream function, including given parameters.
Show hintHide hint
Consider how stream functions relate to areas and velocities.
Question 6.
Analyze how changes in gravitational field (i.e., from Earth to Mars) would impact body forces on a fluid system.
Show hintHide hint
Think about how gravity influences fluid behavior in environments with differing gravity.
