Find the height of liquid level if you use water instead of mercury in the barometer

Hey there,

Lets determine the height of liquid level if you use water instead of mercury in barometer.

For mercury at sea level, the height is :

H = 76cm of Hg

Now by applying formula for pressure-

Pressure = p×g×H

Where H is 76cm, p is density of mercury = 13600 kg/m³

So, P (watercolumn) = P (Hg water)

Thus, we have:

Therefore, height is 1033.6 cm
