Unformatted text preview: ⁄ = 7791 sec Solution: Given data: Maximum CO concentration, Background concentration = Wind speed (u) = 0.5 m/s Mixing height (h) = 100m X = 3 Km = 3000 m Y = 3 Km = 3000 m We know that, ( ⁄ )=( ) ⁄ Or, m = 450 g/sec = ( ⁄ ) Solution: Given data, P = 0.15 According to power law wind profile, ⁄ (⁄ ) ⁄ ( ⁄ ) The wind at 100 m height is 1.414 times stronger than the wind at 10 m. Solution: Effective height = 50 m Ground level concentration of the pollutanat = 300 (positoned directly downwind to point of concern) ( ⁄ C (x,y,z) = ( ⁄ ⁄ ) ( ) ( ) At ground level, ( ⁄ (x,y,z) = ( ⁄ ⁄ ) ..............
