Question

An industrial stack emits 100 g/s of CO at an effective height of 'H', where the wind speed is 5 m/s. At 3 km distance downwind, the values of dispersion coefficient in y- direction and z-direction are 50 m and 25 m, respectively. The CO concentration at the centerline of the plume at 3 km distance downwind is ________ $mg/m^3$ (rounded off to 2 decimal places)? Use Gaussian plume model and value of $\pi$ = 3.14. Neglect reactions and the ground effect of plume in the calculations.

Answer 1

The correct answer is : 2.50 to 2.60
