Question 1.
What happens to the velocity of a fluid in a converging nozzle?
Show hintHide hint
Think about the principle of continuity.
Question 2.
Define local acceleration in fluid dynamics.
Show hintHide hint
It differs from convective acceleration.
3Question 3.
What happens to the fluid velocity in a converging nozzle?
- Decreases
- Increases
- Remains constant
Show hintHide hint
Think about how mass must be conserved in fluid flow.
4Question 4.
True or False: Convective acceleration is the only type of acceleration in fluid dynamics.
- True
- False
Show hintHide hint
Recall the definitions of different acceleration types.
Question 5.
Given a flow through a nozzle with initial velocity 'V0' at the entrance, calculate the exit velocity 'Vx' using the principle of continuity and assess the acceleration.
Show hintHide hint
Refer to equations that relate velocity and cross-sectional area.
Question 6.
Analyze the acceleration field in a two-dimensional flow around a circular object, deriving the equations for acceleration at specified points.
Show hintHide hint
Consider the components of velocity in polar coordinate systems.
