Great, we can start right away.
As I previously stated, I have a problem with the NIST fire simulations failing to debunk
Danny Jowenko's contention that in his professional opinion,
there is absolutely no way fire caused the collapse of WTC7.
The NIST fire simulations indicate that floor 12 and floor 13 of WTC7 suffered from the greatest amount of heat energy.
Using NIST's Figure 9-13 from NCSTAR 1-9's fire simulation chapter, the NIST argues that on floor 12, a heat release rate of 200 MW was sustained
for over
2 hours from about 3 p.m. onward.
The NIST figure 9-11, indicates that fully developed fires covered an area of 750 square meters between 3 p.m. and 5 p.m.
My problem here is, the NIST used a fuel loading factor of
32 kg per square meter for their floor 12 simulations.
The NIST's heat release rate of 200 MW sustained for over 2 hours implies a total energy release of 1,440 GJ.
To do this, we have to assume that the combustible material on floor 12 of WTC7 released 20 MJ/kg.
Over an area of 750 square meters, that would represent the combustion of 72,000 kg of office material.
In other words
96 kg per square meter.
Knock the NIST time estimate down to
40 minutes, instead of 2 hours, and then their 32 kg per square meter fuel loading factor becomes in agreement with the 12th floor fuel load that the NIST has assumed.
You can only imagine how this grave error would wreak havoc with the NIST computer simulation results.
Once you've resolved this conflict (without breaking a sweat of course), I have some more issues to present regarding
the validity of the NIST fire energy estimates.
