A nasty gaseous air pollutant is emitted at a rate of 55.5 kg/s from IPollute Chemical's main stack near Dallas. The conditions on a certain day are: It is a cloudy summer day The sun is at 27.2 degrees above the horizon The average wind speed is 2.53 m/s blowing directly from west to east. There is concern about the air quality at a highly populated downwind location 1.19 km east of the plume. The location of concern is not exactly along the centerline of the plume, but at y = 42.7 m off the plume centerline horizontally and at z = 34.9 m below the plume centerline vertically. Calculate the mass concentration of this chemical at the location of concern in units of mg/m3. Then use those steps to solve for the following problem: A nasty gaseous air pollutant is emitted at a rate of 36.9 kg/s from IPollute Chemical's main stack near Dallas. The conditions on a certain day are: It is a clear summer day The sun is at 69.9 degrees above the horizon The average wind speed is 1.71 m/s blowing directly from west to east.
