Blaise Pascal duplicated Torricelli's barometer using a red Bordeaux wine of density 969 kg/m3, as the working liquid...What was the height h of the wine column for normal atmospheric pressure in meters?

Density of mercury : 13,6 g/cm^3 = 13,6 tons/m^3
Height of mercury to equalize air pressure : 760 mm = 76 cm
Density of wine : 969 kg/m^3 = 0,969 tons/cm^3 = 0,969 g/cm^3
Now if we were to use the wine instead of mercury:
Let "x" be height of wine in the same tube:
13,6 . 76 = 0,969 . x
x = (13,6 . 76) / 0,969 = 1066,67 cm
Hope this helps..
Cheers..

Air pressure is 760 mm of Hg or 14.7 psi. If the area of the tube is 1 cm^2 or 1 in^2, how high (long) must the column be to equal that mass?

Diameter of tube?
