The Fissore Group has a power plant industry that emits SO2 in the combustion chamber, fuel used in the power plant contains 8% of Sulphur. This power plant has a stack containing an effective height of Xm. Calculate the wind speed or 300m. Here, an anemometer on a 10 m pole measures 2.7 m/s of wind and it is a cloudy summer day at the site. The area of the industry is about 50 acres and located on plain land. The capacity of the power plant is 2000 MW, with a 46% efficiency. The plant can emit SO2, at the legally allowable rate of 0.52 lb SO2, per million Btu of heat into the plant and disperse along the wind direction. Calculate the ground level concentration of SO2 at 5 m directly downwind. Show the results in ppm. Here, 1000 MW - 10° kW, 1 KWh - 3412 Btu, 1 kg - 2.204 lb. Consider the stability class is C (to get sigma y, and sigma z).
