2. A Paper company will build a mill 1 km from a residential area. It will emit 40 g/s of hydrogen sulfide, which has an odor threshold of 0.1 mg/m°. Winds at the stack height is 4 m/s blowing toward the residence area. What minimum stack height should be used to ensure concentrations are not more than 0.1 times the odor threshold at the plume center line for a class B stability conditions. Design the stack height assuming no plume rise and to be conservative, use the lowest wind speed.
