A stack emits 100 g/s of SO2 with an effective height of 50 m. Wind speed is 5 m/s, and at a certain downwind distance y = 100 m and z = 50 m. What is the ground-level centerline concentration? (C = Q/(π y zu) · (-H2/2 z2))
- 1273 g/m3
- 386 g/m3
- 772259 g/m3
- 772 g/m3
Answer
D. 772 g/m3
Solution
C = 100/(π × 100 × 50 × 5) × (-0.5) = 0.001273 × 0.6065 g/m3 = 772 g/m3.
