Problem 6 Consider a box model for an airshed over a city that is 1x105 meters on each side, with a mixing height of 1,200m. Winds with no ambient SO₂ blow at 4m/s against one side of the airshed above the city. SO₂ is emitted within the city at a rate of 20kg/s, regardless of city surface area. If SO₂ is considered to be a conservative pollutant, estimate the steady-state concentration of SO₂ in the airshed over the city. Answer: 41.7 µg/m³

![Problem 6
Consider a box model for an airshed over a city that is 1x105 meters on each side, with a mixing
height of 1,200m. Winds with no ambient SO₂ blow at 4m/s against one side of the airshed
above the city. SO₂ is emitted within the city at a rate of 20kg/s, regardless of city surface area.
If SO₂ is considered to be a conservative pollutant, estimate the steady-state concentration of
SO₂ in the airshed over the city.
