All other factors being equal, the height of the column in a barometer is inversely related to the density of the material in that column. So we can write H = h (Rho/rho); where h = 745 mm Hg, H = ? mm in water, Rho = 13550 kg/m^3 Hg density and rho = 997 kg/m^3 water density.

So we have H = 745*(13550/997) = 10125.12538 mm ~ 10.1 m when all other factors are equal. ANS.

What does mm Hg mean for compression stockings?

"mm Hg" stands for millimetres of mercury. Atmospheric pressure was measured in terms of the height of a column of mercury that it could support and by extension, mm Hg became a unit for measuring pressure.


A gas occupies 30 L at 760 mm Hg what is its volume at 350 mm Hg?

The phrase "760 mm Hg" is physicists' shorthand for "an atmospheric pressure equal to that needed to support a column of mercury [chemical symbol Hg] of length 760 mm". This is approximately average atmospheric pressure at sea level. As the pressure decreases from "760 mm Hg" to "350 mm Hg", the volume of the gas will increase (assuming a constant temperature). The new volume can be determined using Boyle's Law: New Volume = 30 x 760 / 350 = 65.143 Litres
