3. Sulfur dioxide is being emitted in a rural area at a rate of 0.90 kg/s from a stack with an effective stack height of 220m. The average wind speed at stack height is 4.8 m/s and the stability category is B. Determine the short-time period, downwind, center-line concentration in micrograms per cubic meter at ground-level distances of 1.0, 2.0 and 4.0 km.

4. What is the expected short-term period ground-level concentration at 150 and 250 m away from the downwind center line for the conditions given in Problem 3?

Module 4: Dispersion of Pollutants 1. Most equations for predicting plume rise contain two terms that account for different physical reasons for the rise. What is the nature of these two terms? 2. Is it justifiable to use a constant value for the effective plume rise for a given situation, or should one in reality, adjust for the distance downwind from the stack? Discuss. 3.

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...

An industrial facility emits toluene at a rate of 10 lb/day. The day is very sunny, with moderate winds (4 m/s). You are interested in the ground-level center line toluene concentration 10 km downwind of the 25 m tall stack (assume a plume rise of 8 m). Calculate the ground-level center line concentration of toluene 10 km downwind.

   1. A stack emitting 80 g/s of NOx has an effective stack height of 100 m. The wind speed is 4 m/s. It is a clear summer day with the sun nearly overhead. The emission is near a human inhabited area. Estimate the ground-level NOx concentration (µg/m3) for the following scenarios:        (a) directly downwind at a distance of 2 km. (b) at the point downwind where the NOx, is a maximum. (hint: use diagram on slide 59). What...

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...
