AZ10 Main Stack 5.182 161,116

AZ11 Annuluar Stack 7.288 230,016

Annuular stack "diameter" is that of a circle with the same area

The temperatures are comparable to previous values.

The resulting stack exit velocities are much less than what WRAP used, 

only only around 5% of what was supplied by ASARCO in July 2013!

circle area = pi * diameter^2 / 4

annulus area = outer circle area - inner circle area = (outer^2 - inner^2)*pi/4

diameter of circle equivalent to annulus area = sqrt(outer^2 - inner^2)

If given diameter is the true outer diameter, then that of a circle equivalent to the annulus area is:

implied

inner outer ==> equivalent

If given diameter is the that of a circle equivalent to the annulus area, then true outer diameter is:

flow = volume / time = area * exit velocity = (pi/4) * diameter^2 * velocity

exit velocity = (4/pi) * flow / diameter ^2

If flow and diameter were used to calculate exit velocity, then using the incorrect one

makes the velocity off by a factor of two here.
