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.

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.

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.

Determine the required ventilation rate for a particle board manufacturing facility operating 24 hours per day. The facility must meet a formaldehyde (HCHO) concentration of 0.10 ppm. It generates 25,000 μg · d–1 · m–2 of HCHO. The facility work space is 30 m × 10 m × 5 m. The exhaust from the building is scrubbed and vented through a 10-tall stack. The ambient air intake contains no HCHO.
