What is the Chimney Effect or Stack Effec

Chimney or Stack Effect is a natural phenomena that is very common in the fireplaces in homes, tall skyscrapers and power plant flue gas stacks. The natural phenomena of the density difference between a hot and cold air column that creates a natural flow through a chimney is called the Chimney effect. Learn more about this in this article.
