The pressure difference or chimney draft can be expressed as: dp ch = h (ρ o-ρ i) a g (1) where. dp ch = pressure draft in the chimney (Pa) h = height of chimney (m) ρ o = ambient outside density of air (kg/m 3) ρ i = inside chimney density of air (kg/m 3) a g = acceleration of gravity (9.81 m/s 2) Since the Ideal Gas Law states that . ρ o T o = ρ i T i . or
