Let's see, what's the easiest way to do this calculation? Scuba divers learn that a depth of 10.3 meters (34 ft) is what it takes to increase the pressure by one atmosphere, which is about 15 psi.
So, let's see, 10 cm is about one hundred times smaller than 10.3 meters. If we make 15 psi one hundred times smaller we get 0.15 psi. That's not anywhere near enough to unflatten a flat tire, in fact, it wouldn't even blow up a balloon, would it?
But it's enough to keep our airways open while we sleep. Great Uncle, it's a miracle! I can't imagine how horrible my life would be without it.
i always thought the old first generation remstar would make a good aquarium pump if it could be stepped down to little hose.
