There is traffic on I-5 as people leave a Seahawks game one fall afternoon. Approximately 12,000 vehicles per hour passing a house 250m away. Each car emits an average of 1.6g/mi of NOx, and winds are blowing at 5.5m/s across 15 towards the house. Assume that NOx is chemically stable (i.e. conservative). Estimate the NO x concentration (in mg/m3 ) at the house. (Use formula 7.48 to determine the dispersion coefficient for your concentration calculation.)
