Doesn't a 747 have four engines?

Fair enough. But then apparently I used the takeoff figure for the amount
of air a jet sucks up, not the cruise figure which is somewhat lower.

The figure you quoted is correct for an RB211, as used on typical 747's.
It's the engines on smaller planes that peak around the same.

Never argue with a warmer. Climategate revealed that the evidence was
faked. But it is a matter of faith with these people. Evidence of
not, they believe in it. Leave them to their delusion
