What is height of a column of water?
Answer:
It depends on how high or deep it is ..! and, as a column the other dimensions are not needed unless you want to find its volume.
In a drinking glass full of water, the column will be about 4 inches high and will exert a pressure of about 0.144psi .
In the sea at a depth of 300 feet, a column of water will be 300 feet high from the sea bed to the surface and will exert a pressure of about 150psi.
A column of atmospheric air from sea level to the edge of space is exerting an atmospheric pressure equal to a column of Mercury 760mm high. (or 14.7 psi...a column of water 10m high will exert the same pressure. and is equal to 1,000g/cm²).
Your question is a little vague, but the height of a column of water is generally a measure of pressure.
In other words, if the pressure at a given point is 8' of water, that is in terms of head, or, it has the same pressure as if a column of water 8' high were on top of it.
Pressures given in feet of head can easily be converted to psi.
Hope this helps
Be more specific. The dimensions of the column are needed as welll as the volume of water.
h= P/pg where h is height of water (m), P is external pressure (Pa), p is density (kgm^-3) and g is acceleration of free fall (ms^-2)
for atmospheric pressure:
h ~ 100,000/(1000*10) = 10m
More information required?
It's 13.6 times as high as a column of mercury. So at 760mm Hg the height of a column of water would be 760 x 13.6 = 10336mm =1033.6cm = 10.336m.
This is why we don't have barometers using water, they'd need to be over 30feet high. 1.5 metres is enough if you use a column of mercury.
