pressures...
Hi Kathie, Craig,
Yes...and, that Atmospheric pressures may be expected to be
less as one increase in elevation; meaning not merely less
Oxygen, but less pressure and density of the Atmosphere
ambiently,
which of course also means, in effect, less Oxygen per given
volume of Atmosphere.
Many Aeroplanes ( and some Cars at one time, or still, )
addressed this by
having ways of admitting a larger volume of Air for their
Engines combustions, as they ascend...
In short, one needs to admit a larger volume of ambient
Atmosphere, per given amount of combustible, as one ascends
in elevation, or, as one has less ambient Atmospheric
pressure...to enjoy the same effect or results as at Sea
Level.
Similarly, if the Barometer indicates 'low' pressure, one
confronts a lesser version of the same consideration...or as
one has with imminently approaching Cyclones or
Hurricanes...
