Unformatted text preview: the minimum altitude for planes to fly safer is 855.59 m. Solution: Given data:
Wind speed = 4.5 m/s
Source strength = 0.25
Assuming the stability condition to be (B)
From notes, figure 4-7,
= 738.97 ( ⁄ ⁄ ( ) ) ⁄ ) Solution: Average speed = 40 Km/h
Number of vehicles = 10,000
Wind speed perpendicular to the highway = 3 m/s
Average CO concentration = 10 g/Km (per vehicle)
( (⁄ ) ( [ ⁄ (⁄ )] Assuming stability condition (F), we get
