Question 1.
What is the definition of an emission factor?
Show hintHide hint
Think about how we measure pollution output.
Question 2.
What does mixing height determine?
Show hintHide hint
Consider its role in dispersion.
3Question 3.
What is the main use of the Gaussian dispersion equation?
- To calculate mixing height
- To model pollutant spread
- To measure water quality
Show hintHide hint
Focus on what modeling implies.
4Question 4.
True or False: Mixing height is irrelevant in pollution dispersion.
- True
- False
Show hintHide hint
Consider why this concept is fundamental to environmental science.
Question 5.
Calculate the dispersion of a pollutant using a known emission factor and mixed concentration at varying heights. Include both environmental and adiabatic considerations.
Show hintHide hint
Use real data if available to ground your calculations in reality.
Question 6.
If a factory emits pollutants at an emission factor of 1.2 kg per ton with a stack height of 25 meters, estimate how far the pollutants would travel before they reach ground level.
