How can you calculate dispersion of a pollutant sourced a stack located inside a cooling tower ?

What's the best way to measure growth rates in House sparrow chicks from day 2 to day 10?

What's the best way to measure growth rates in House sparrow chicks from day 2 to day 10? Since, the growth curve from day 2 to 10 won't be like the "Logistic curve" it might not follow logistic...

What techniques can I use to determine the miscibility of polymer blends?

The term miscibility refers to the single-phase state in thermodynamics. I do not mean the compatibility of different components. To determine the miscibility I know several techniques such as...

We have all necessary source information and meteorological dataset. The critical point what should be taken the stack height and diameter?

Yadollah Tavan

please refer to ALOHA/PHAST software, these softwares use the Gaussian model to predict pollutant distribution.

Thanks your references. We already have been using developed softwares to predict pollutant distirbution. My question is very specific to take some critical inputs for softwares.

When exhaust gas speed and volume from the stack in the natural-draft cooling tower is less than that from the natural-draft cooling tower, and the pollutants are assumed passive (no reactive),　pollutants disperse from the natural-draft cooling tower.

Please refer to Handbook on Atmospheric Diffusion, Hanna et al.(1982) US DOE.
