5.2. Fluid Mechanic Models

Try these first

1. 1.

   What is a point source in pollution modeling?

   Hint

   Think of something you can physically point to.

2. 2.

   Define turbulence in fluid dynamics.

   Hint

   It’s the opposite of smooth flowing.

3. 3.

   What type of source is a factory smokestack classified as?

   • Point Source
   • Line Source
   • Area Source

   Hint

   Consider how it's defined.

4. 4.

   True or False: The Gaussian dispersion model assumes pollutants disperse uniformly.

   • True
   • False

   Hint

   Think about the reality of airflow.

5. 5.

   An area source produces pollutants over a broad area. Describe how you would model it and the data you would need.

   Hint

   Think about the broader impact on the community.

6. 6.

   Compare and contrast AERMOD and CALPUFF based on their applications in different scenarios.

   Hint

   What distinguishes steady versus transient modeling?
