Consider a box model for an air shed over a city that is 1 X 105 m on a side, with a height of 1200 m induced by a temperature inversion. Winds with no SO2 blow at 4 m/s agains one side of the box. SO2 is emitted in the box at the rate of 20 kg/s.

(a) If SO2 is considered conservative, estimate the steady state concentration in the airshed.

(b) Assuming that SO2 emissions only occur on weekdays. If emission stop at 5 pm on Friday, estimate the SO2 concentration at midnight.

(c) If SO2 emissions begin again on Monday morning at 8 am, what would the concentration be by 5 pm?
