<br />in which Tl ,= the flame temperature and V1 flame volume; T2 = ambient air
<br />temperature and V2 ambient air volume; and Ts = effluent temperature and
<br />Vs effluent volume.
<br />Take the following values and solve Eq. 1 for V2:
<br />

<br />With these v,alues, V2 = 26.8, which may be called a dilution factor.
<br />With 12.5:mg of iodine whichwill remain as iodine vapor per cu mat 2,300"
<br />F, and an ambient air temperature of 70" F, there will be 0.47 mg of iodine
<br />per cu m of effluent at the point where the effluent temperature is 150" F.
<br />If an ambient air temperature of 0" F is assumed, a concentration of 0.87
<br />mg of iodine per cu m of effluent will be found at the point where the effluent
<br />temperature is 150" F.
