To save money on buying mercury you build a barometer using water as the fluid inside the column. approximately, how tall is your barometer? (hints r(mercury) =1.36 x 10^4 kg/m^3 and r(water) = 1.00 x 10^3 kg/m^3).

To solve this problem we need to use the concepts related to fluid density. Since we need to know a height point of two different liquids, their pressures must be equal, so

Where,

Density

g = Gravitational acceleration

h = Height

Our values are given as,

Standard mercury pressure at 1atm, the barometer height is 760.2mm.

Replacing we have,

Therefore the tall of the barometer would be 1033.87 (Inconvenient compared with the Mercury Barometer)
