A car idling emits NO_xat a rate of 2 g/sec. Assuming an effective “stack” (tailpipe) height of 2 feet, Class C stability, and a wind speed at tailpipe height of 0.5 m/sec, estimate the ground-level concentration of NO_x100 m directly downwind. Terrain is rural.

A snoke stack with an effective height of 45 m emits SO2 at a rate of...

A snoke stack with an effective height of 45 m emits SO2 at a rate of 8 kg hr -1. What is the contribution of this stack to ground-level SO2 concentrations at a school yard 950 m downwind, if wind speed is 1.5 m s-1 on a sunny winter day? Assuming unlimited mixing height, and the atmosphere stability is unstable?

A facility emits 18 g SO2 /s at an effective height of 60m. On a cloudy night, an anemometer at a height of 10 m above ground measures the wind-speed at 3.2 m/s. Predict the ground-level SO2 concentration 0.4 km directly downwind. (60 pts.) What does the plume look like? Sketch a plot. (20 pts.) What would the plume look like if there were an inversion layer at an elevation of 100 m? Sketch a plot. (20 pts.)

A chimney with a design stack height of 200m is emitting SO2 at a rate of 600g/s on a sunny day in summer, with moderate wind speed at the stack altitude. the volumetric flow rate is measured as 26m3/s, and the wind speed at a height of 10m above the ground is 5m/s. Calculate the grout level concentration of SO2 1km downward of the stack

The rate of emission of SO2 from the stack of a power plant is 150 gm/sec. The stack height is 50 m. Calculate the effective plume height on a sunny September day when the wind velocity is 5 m/sec. Use Class B stability. The effluents are being released at 10m/s and at a temperature of 310oK. The atmospheric temperature is 293oK. The stack diameter is 0.5 m
