How do I calculate an appropriate chimney height to ensure

Density of gases at the outlet of the chimney – Flue gases density at the outlet of the chimney is dependent upon the temperature of flue gases exiting the chimney, measured in (Kg/m^3). Height of chimney – Draft developed by chimney is directly proportional to the height of the industrial chimney, so height the chimney, more will be the draft. Chimney height is measured in (m).
