Re: [Phys-l] air pressure question



Well, it seems in this lecture that he is making the same mistake that I and others were regarding Bernoulli. In particular, he compares the still air in an atomizer with the moving air flowing above it and says the flowing air therefore has a lower pressure. But didn't we learn in our conversations here that it is wrong to compare moving air in one place with still air in another? Doesn't Bernoulli apply only to a continuous column of air?

Still doesn't answer my question about the Floogle, as it's called in some places.

And you may notice that he catches himself at the too easy Bernoulli
