2. A 1000 MW power plant burns 10,000 metric tons of 1.5% sulphur coal per day. The flue gases are emitted into the atmosphere through a stack of height 200m. The diameter of the stack is 5m. The velocity and the temperature of the plume at the exit is 10m/s and 120C. Assume ambient temperature is 15C and wind speed at the stack is 3 m/s. The horizontal and vertical dispersion coefficients at 5km downwind of the stack are 55 and 32m. Calculate the ground level SO2 concentration along the plume centerline at a downwind distance of 5 km from the stack when the environmental lapse rate is: (a) Less than the adiabatic lapse rate (10) (6) Equal to adiabatic lapse rate (5) 2.
