It's time to build a density tower! Different liquids poured into a clear container that stay separated ie oil and water. With a few of the liquids that are on the list we can demonstrate the ...

A common way of measuring the level of liquid in a tank places a low-pressure sensor at the bottom. The pressure readout is the product of the liquid column height times the density of the liquid. As ...

WHEN a liquid of slightly greater density than water is poured into a shallow layer of the latter, it is often possible to produce the formation shown in the accompanying photograph, in which the ...
