12.2.3. Computing Accelerations in 2D Flow

Try these first

1. 1.

   Define local acceleration in the context of fluid dynamics.

   Hint

   Think about changes in speed at a location.

2. 2.

   What is meant by convective acceleration?

   Hint

   Consider how moving through varying fields influences speed.

3. 3.

   What is local acceleration?

   Hint

   Think about acceleration as something happening in a localized area.

4. 4.

   True or False: Convective acceleration is irrelevant in steady flow.

   Hint

   Consider motion through a velocity field.

5. 5.

   Given a variable velocity profile in a converging nozzle, derive the expression for local and convective accelerations and compute them for specific velocity values.

   Hint

   Refer to the initial derivation for proper formulation.

6. 6.

   Analyze the effects of increasing diameter on the acceleration of fluid in a nozzle and predict potential problems in flow behavior.

   Hint

   Consider continuity and Bernoulli's principles in your analysis.
