Question 1.
What does the steady state assumption mean?
Show hintHide hint
Think about a scenario where conditions are stable.
Question 2.
Name the three dimensions in which pollutants are dispersed.
Show hintHide hint
They correspond to spatial dimensions.
3Question 3.
What is the meaning of the steady state assumption?
- Pollutant concentration stays constant
- Pollutant concentration fluctuates
- Pollutant concentration increases over time
Show hintHide hint
Think about the implications of a fixed amount of pollutant being released.
4Question 4.
True or False: In a Gaussian distribution, the mean represents the highest concentration of pollutants.
- True
- False
Show hintHide hint
Recall the properties of a bell curve.
Question 5.
Given a pollution source releasing 10 kg of a pollutant per hour, estimate the concentration at a distance of 5 meters from the source in a steady state scenario with known diffusion coefficients.
Show hintHide hint
Refer to the equations linking the emission rate to concentration based on distance.
Question 6.
Analyze a real-life scenario where a factory operates under varying emission rates and discuss how this affects the validity of steady state assumptions.
Show hintHide hint
Consider external factors such as weather or regulations.
