(17 pt) Suppose a bonfire emits CO at the rate of 20 g/s on a clear night when the wind is blowing at 2 m/s. If the effective stack height at the fire is 6 m: (a) (6 pt) What would you expect the ground-level CO concentration to be along the centerline at 400 m downwind (in mg/m3 )? (b) (6 pt) Estimate the maximum ground-level concentration using empirical method (in mg/m3 ). (c) (4 pt) Estimate the maximum ground-level...

A new industrial facility is proposed at a location 5 km upwind from an existing multi- family residential development. The exhaust of the factory emits chloropicrin at the rate of 2500 g/s. The detection threshold for chloropicrin is 10 μg/m2. The atmospheric stability conditions for the area changes between stability classes D&F and the average wind speed is 5.0 m/s. Would should be the minimum recommended height for the smoke stack of that industrial facility? (Hint: we are concerned with...

A power plant burns coal with 2 % sulfur. Emissions occur through a 70-m tall 02. stack with a diameter of 1.5 m. The exit velocity and temperature are 15 m/s and 340°C, respectively. The atmospheric conditions are temperature of 28°C and pressure of 90 kPa. On a clear summer aftemoon with a wind speed of 2.8 m/s at 10-m level, the ground level SO concentration is measured to be 143 ug/m at a point 2.5 km downwind and 300...

An existing rural power plant has been found to produce an SO2 concentration of 30 mg/m3 at a distance of 800 m directly downwind from stack when the wind is 4 m/sec from the north during a class C stability situation and the atmospheric temperature is 20℃. At a later date, another plant is built 200 m to the west of the original plant. It burns 4000 lb/hr of fuel oil contains 0.5 percent sulfur. The second plant has a...
