12.2.1. Streamline Patterns and Acceleration Field

Try these first

1. 1.

   What happens to the velocity of a fluid in a converging nozzle?

   Hint

   Think about the principle of continuity.

2. 2.

   Define local acceleration in fluid dynamics.

   Hint

   It differs from convective acceleration.

3. 3.

   What happens to the fluid velocity in a converging nozzle?

   • Decreases
   • Increases
   • Remains constant

   Hint

   Think about how mass must be conserved in fluid flow.

4. 4.

   True or False: Convective acceleration is the only type of acceleration in fluid dynamics.

   • True
   • False

   Hint

   Recall the definitions of different acceleration types.

5. 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.

   Hint

   Refer to equations that relate velocity and cross-sectional area.

6. 6.

   Analyze the acceleration field in a two-dimensional flow around a circular object, deriving the equations for acceleration at specified points.

   Hint

   Consider the components of velocity in polar coordinate systems.
