12.1.2. Computing Acceleration

Try these first

1. 1.

   Define Local Acceleration in fluid dynamics.

   Hint

   Consider how velocity changes at a stationary point.

2. 2.

   What condition represents Steady Flow?

   Hint

   Think about whether the flow parameters are constant.

3. 3.

   What is Velocity Distribution?

   • A change in pressure
   • Variation of flow velocity
   • Temperature gradient

   Hint

   Think about how velocity changes through different sections of flow.

4. 4.

   In steady flow conditions, local acceleration equals what value?

   • True
   • False

   Hint

   Consider the meaning of stability in flow dynamics.

5. 5.

   A nozzle experiences a velocity increase from 5 ft/s to 25 ft/s. If the nozzle length is 3 ft, compute the acceleration experienced in both conditions.

   Hint

   Remember to divide the change in velocity by the distance.

6. 6.

   Discuss the implications of ignoring local accelerations in a design for fluid machinery.

   Hint

   Reflect on what local instability could result in for machinery functionality.
