Q = chimney draught/draft flow rate, m 3 /s; A = cross-sectional area of chimney, m 2 (assuming it has a constant cross-section) C = discharge coefficient (usually taken to be from 0.65 to 0.70) g = gravitational acceleration, 9.807 m/s 2; H = height of chimney, m; T i = average temperature inside the chimney, K; T e = external air temperature, K.
