9-30. On a clear summer afternoon with a wind speed of 3.20 m/s, the particulate concentration was found to be 1,520 mg/m3 at a point 2 km downwind and 0.5 km perpendicular to the plume centerline from a coal-fired power plant. Given the following parameters and conditions, determine the particulate emission rate of the power plant: Stack parameters: Height 5 75.0 m Diameter 5 1.50 m Exit velocity 5 12.0 m/s Temperature 5 3228C Atmospheric conditions: Pressure 5 100.0 kPa Temperature 5 28.08C
