The wind velocity at standard 10 m elevation is 7 m/s and stability class is B in an rural area. Stack temperature is 200 C and the ambient atmosphere temperature is 20 C. The stack diameter is 6 m. The stack velocity is 5 m/s. A)What would you estimate the velocity to be at the stack height of 120 m elevation based on Table 3-3? B) check out if there is stack downwash? wwwm C) If there is stackdownwash, what is the corrected stack height? wwwww mmm Formula Sheet: Molecular weights S:32 N:14 0:16 Standard T:25 C Normal T:0 C = (²-)² Vs/u<1.5 then there is stack downwash h's = hs + 2ds Corrected stack height: Table 3.3 C (x, y, z): Stability Category A B C D E F 41 -1.5 Us Επισ, σε U 2₂ Rural Area 0.07 0.07 0.10 0.15 0.35 0.55 Q - exp - (2,7){exp[-(2-²)] + exp[- (2+12²)]} P Urban Area 0.15 0.15 0.20 0.25 0.30 0.30 The wind velocity at standard 10 m elevation is 7 m/s and stability class is B in an rural area.
