Howdy, all - first post here.
I'm a HS physics teacher, and I taught fluid mechanics for only the second time this year. It never was my strong suit.
I thought I more or less knew what I was doing, but when I was having dinner with my parents the other day, they brought up some comment that Romney made about opening the windows on an airplane. So I started talking about how that in addition to reduced air pressure at high altitudes, you'd also have reduced air pressure due to the Bernoulli effect, since air outside the plane is whipping by at 800 kph, which would contribute to sucking more air out of the plane.
But later, I started wondering. From the point of view of the air, the plane is moving at 800kph. From that point of view, the air in the plane is moving fast, would have lower pressure, and air should get sucked into the plane.
What am I missing?
