Estimate value of emission rate divided by the wind speed

Reference no: EM13299372

A ground level source is emitting pollution. An air sampler is located 1 km downwind and 0.5km crosswind of the source measures the concentration of the pollutant ant ground level as 10 micrograms/cubic meter. At ground level teh temperature is 30 degrees C. At a height of 2000 meters, the temperature is 5 degrees C. The following values may be helpful: for a stable atmosphere sigma z=13 m; sigma y=33 m. For an unstable atmosphere sigma z=500 meters, sigma y=200 meters. Estimate the value of the emission rate divided by the wind speed (Q./u) in grams per meter, expressed to one decimal place.
