5.5.4. Uniform Flow Velocity Distribution

Try these first

1. 1.

   Define steady flow and give an example.

   Hint

   Think about fluid flow without time change.

2. 2.

   What is Bernoulli's equation used for?

   Hint

   Consider its applications in pressure calculations.

3. 3.

   What is uniform flow?

   • A flow with varying speed.
   • A flow with constant velocity across a section.
   • A flow affected by turbulence.

   Hint

   Consider how speed behaves across a flowing fluid.

4. 4.

   True or False: In steady flow, the pressure at a point can change over time.

   • True
   • False

   Hint

   Think about what 'steady' signifies for fluid behavior.

5. 5.

   A water pipe with varying diameters shows that the flow speed increases as the pipe narrows. How would you calculate flow rate using uniform flow assumptions?

   Hint

   Remember, A = π(d/2)² for area.

6. 6.

   Assume a building faces winds that create varying air pressures on different sides. How would you apply Bernoulli's principles to assess the structure's integrity?

   Hint

   Set up your control volumes carefully around pressure points.
