Question 1.
Define local acceleration in your own words.
Show hintHide hint
Think about how speed varies for an individual particle.
Question 2.
What is convective acceleration?
Show hintHide hint
Consider how the movement of a car through traffic gives different speeds.
3Question 3.
What does local acceleration describe?
Show hintHide hint
Remember to focus on the aspect of time at a specific location.
4Question 4.
Is convective acceleration present in a steady flow?
- True
- False
Show hintHide hint
Think about gradients in the velocity field.
Question 5.
Given the velocity field V = yz, find the local and convective accelerations at point (1,1,1).
Show hintHide hint
Start by identifying each definition of acceleration.
Question 6.
Consider a fluid that behaves such that v = -3x, derive both types of acceleration at a given point and discuss implications for steady flow.
Show hintHide hint
Think about the role of time in your factors.
