Discussion
Match each quantity in List I with how it varies in List II.
List I
A. Maximum ground level concentration
B. Exit velocity at constant flow
C. Plume rise
D. Distance to the maximum
List II
1. As the inverse square of stack diameter
2. As the inverse square of effective height
3. Increases with effective height and stability
4. Inversely with wind speed
Select the correct match.
Answer: A
Correct answer: A-2, B-1, C-4, D-3
Maximum concentration varies as \(1/H_e^2\) (2). Exit velocity as \(1/d^2\) at constant flow (1). Plume rise inversely with wind speed (4). And the distance to the maximum increases with effective height and with stability (3).
