WebNov 25, 2013 · Velocity of gas in a stack (V) = Q/kA where k is the coefficient of velocity (0.3-0.5),Q is the volume of gas to be handled in (cfs), V is the velocity (ft/sec) and A is the the cross sectional area of the chimney or stack (ft*2). If a stack is used (as opposed to a chimney) the velocity will be higher due to the smoother internal surfaces. Webeffective stack diameter and using the parameters listed in the ISC model setup guideline. The SCREEN3 flare option assumes an effective stack gas exit velocity (vs) of 20 m/s and an effective stack gas exit temperature (Ts) of 1,273 Kelvin, and calculates an effective stack diameter based on the heat release rate.
