1.5. Non-Uniformity Near Solid Boundaries

Try these first

1. 1.

   Define uniform flow.

   Hint

   Think about the characteristics of flow speed.

2. 2.

   What happens to fluid velocity at a solid boundary?

   Hint

   Consider the effects of viscosity.

3. 3.

   What defines uniform flow?

   • It is constant in time and space
   • It is variable in time and space
   • It is constant in time only

   Hint

   Remember the distinction between time dependency and space dependency.

4. 4.

   True or False: In a non-uniform flow, velocity can be the same at different points.

   • True
   • False

   Hint

   Think about how velocity changes throughout a fluid body.

5. 5.

   Consider a river flowing over a flat surface and reaching a dam. Describe how the flow velocity changes as it approaches the dam, specifying uniform and non-uniform characteristics.

   Hint

   Reflect on the impact of solid structures on flow behavior.

6. 6.

   Design an experiment to measure fluid velocity at various points in a channel. How would you determine if the flow is uniform or non-uniform?

   Hint

   Consider the setup of measuring devices and locations.
