A smoke stack emitting 75 g/s of CO2 has an effective stack height of 250 m. The windspeed is 4 m/s at 10 m, and it is a clear summer day with the sun nearly overhead. Estimate the ground-level CO2 concentration a. directly downwind at a distance of 2 km (in g/m3). b. at the point downwind where CO2 is a maximum (in g/m3). c. at a point located 2 km downwind and 0.1 km off the downwind axis (in g/m3). What if there was another smoke stack with an effective stack height of 100 m located at a downwind distance of 600 m from the 1st stack. The 2nd smoke stack is also emitting CO2 at the same 75 g/s rate and all other air conditions remain constant. Calculate the overall ground level concentration 2 km downwind (from the second smokestack) on the center line

Answer rating: 100% (QA)

To estimate the groundlevel CO2 concentration at different points downwind of the smoke stacks we can use the Gaussian Plume Model This model assumes steadystate conditions and that the plume is wellm... View the full answer
