This iinowledge of the shape of the jet renders it possible to deter-mine the efficiency of any chosen nozzle distance from the smallestsection of the stack, as we have already shown in what we base our calculations upon a flare of I in , the correspondingdistance at which the smallest cross-section of the stack is justfilled by a continuous jet of steam is shown in the following tablefor the several nozzle diameters: Smallest diameterof stack. 80 75 No
