Show hintHide hint
Think about situations in which fluids do not change density.
Question 2.
Define a streamline.
Show hintHide hint
Consider how water flows in a river.
3Question 3.
What does Bernoulli's equation describe?
- Energy conservation in fluid flow
- Density variations in fluids
- Viscous effects in flows
Show hintHide hint
Consider what happens to fluid energy as it flows.
4Question 4.
True or False: Velocity potential functions are applicable in rotational flows.
- True
- False
Show hintHide hint
Think about the conditions under which these functions are defined.
Question 5.
Consider a fluid flowing between two parallel plates with a constant pressure gradient. Derive the velocity profile assuming steady-state incompressible flow.
Show hintHide hint
Don’t forget the simplifications you can make!
Question 6.
How would the behavior of the streamlines change if the flow became rotational due to turbulence introduced?
Show hintHide hint
Consider the implications of added energy in the system.
