Would a bicycle pump work underwater, with its air-input being above water?
On one side we have air pressure basically the same as at the surface, on the other side of the piston we have the water pressure which depends on the depth. … Because it seems simpler right now I'm using Bar instead of Pascal for pressure.
Per 10m depth we have one Bar of pressure added. 1 Bar is 1kg/cm^2. …

Wave propagation around the globe
I've been able to detect the pressure wave of the tonga volcanic eruption with the atmospheric pressure sensor here in switzerland (about 17Mm away). I've detected a swing of about +1.2hPa and -1hPa. … So my question is:
How does a pressure wave traveling within the atmosphere around the globe behave?
How long/far does the inverse square law hold true? …
