On a clear winter night, a wind speed of 2.5 m/s was measured on a 10-m pole. The centerline ground-level concentration of SO2 was found to be 198 μg/m3 at a point 2.8 km downwind from a coal-fired power plant. The effective stack of the power plant is 85 m.

a.Determine the atmospheric stability category of the day.

b. Estimate the windspeed at 85 m (in m/s).

c. Determine the SO2 emission rate (kg/s) of the power plant in kg/s by using the Table 7.8 on pg. 457.

On an afternoon with moderate incoming solar radiation and an average wind speed of 2.5 m/s at a height of 10 m above the ground surface, a power plant emits sulfur dioxide at a rate of 1 kg/s. The effective height of stack is 130 m. The wind speed at the effective stack height is 2.8 m/s. Calculate the concentration (in μg/m3) of sulfur dioxide at ground elevation, directly 3 km downwind from the stack (show hand calculation for this...
