Question

You are located downwind from two oil burning power plants in rural areas. One is located 0.3km NNE of your location and burns 1400 kg of 0.5 percent sulfur oil per hour. The second plant is located 0.5 km NNW of you and burns 1600 kg/hr of fuel oil containing 0.75 percent sulfur. Aumme that both plant stakc have an effective height of 40m. The wind is blowing from the north at 3.3 m/s. For a class B stability condition, what is the SO₂ concentration at your location at ground level, in micrograms per cubic meter? The wind speed is at the standard height of 10 m

Expert Solution

Step 1: Introduction:

We may use the following formula to get the ground-level SO2 concentration at your location:

$C space equals space left parenthesis F 1 space cross times space H 1 space plus space F 2 space cross times space H 2 right parenthesis space divided by space left parenthesis pi space cross times space u space cross times space sigma z space cross times space sigma y space cross times space H right parenthesis$

where:

C is the SO2 concentration in micrograms per cubic meter (μg/m³)
F1 is the emission rate of the first power plant in kilograms per hour (kg/h)
H1 is the effective height of the first power plant in meters (m)
F2 is the emission rate of the second power plant in kilograms per hour (kg/h)
H2 is the effective height of the second power plant in meters (m)
u is the wind speed at the standard height of 10 meters in meters per second (m/s)
σz is the vertical dispersion parameter in meters (m)
σy is the lateral dispersion parameter in meters (m)
H is the mixing height in meters (m)
