Question 1.
Define a streamline and provide one example.
Show hintHide hint
Think about the direction of fluid movement.
Question 2.
What does it mean for a flow to be irrotational?
Show hintHide hint
Consider how fluid behaves in a smooth motion.
3Question 3.
What is a streamline?
Show hintHide hint
Think about what path a particle in the fluid would take.
4Question 4.
True or False: In irrotational flow, the velocity potential can be derived from the gradient of a scalar function.
- True
- False
Show hintHide hint
Consider how potential flows are represented mathematically.
Question 5.
Consider fluid flowing over a curved surface. Analyze how the presence of the wall affects the streamlines and potential function profiles.
Show hintHide hint
Reflect on how speed and elevation potential are related in this context.
Question 6.
Given a simple two-dimensional incompressible flow, derive the conditions under which the Navier-Stokes equations can simplify to Euler equations.
Show hintHide hint
Focus on what makes a flow inviscid and how that affects terms in the equations.
