What is the pressure of the 760mm high vertical column of mercury?

The pressure of the vertical column of mercury with a height of 760 mm is normal atmospheric pressure and is equal to 101 325 Pa.

To check, we calculate the hydrostatic pressure of mercury at a depth of 760 mm:

Р = ρ * g * h, where ρ is the density of mercury (ρ = 13600 kg / m³), g is the acceleration of gravity (we take g = 9.81 m / s²), h is the height of the liquid column (h = 760 mm = 0.76 m).

P = ρ * g * h = 13600 * 9.81 * 0.76 = 101 396 Pa.

Answer: The pressure of a vertical column of mercury with a height of 760 mm is 101 325 Pa (101 396 Pa).
