A power plant emits 95 g/s of SO2 from an effective stack height of 60 m. The wind speed is 3 m/s and the solar insolation is slight.
A) Estimate the ground level SO2 (ug/m^3) at a point 4 km directly downwind of the power plant
B) Estimate the ground level SO2 (ug/m^3) at a point 2 km downwind and 0.6 km off the axis
C) If the temp is 10 C and the pressure is at 1 atm, does the air quality of A and B meet the NAAQS requirement of 0.14 ppm?
