The assumptions made won't have much effect on the calculation, and
neither will rounding error. The biggest error probably comes from the
100% combustion; from the smell they make, most jets give out quite a
bit of unburnt fuel. Right ball park though.

You only smell them when they're on the ground (for the most part)
and operating at partial throttle and low Tit.
When they're operating at higher throttle settings and higher
temps the combustion is more complete.
The higher combustion temp also forms NOx's.
