Question

What height of water column produces the same pressure as a 760mm high column of mercury?

Answer 1

How high in meters must a column of water be to exert a pressure equal to that of a 760-mm. ... The density of water is 1.0g/mL , whereas that of mercury is 13.6g/mL .

Answer 2

Hey dear,

● Answer -
hw = 1034 cm

● Explaination -
# Given -
ρm = 13.6 g/cm^3
ρw = 1 g/cm^3
hm = 760 mm Hg = 76 cm Hg
hw = ? cm H2O

# Solution -
Let P be the atmospheric pressure.
P = hw.ρw.g = hm.ρm.g
hw = hm.ρm / ρw
hw = 76 × 13.6 / 1
hw = 1034 cm

Therefore, height of water column would be 1034 cm of water.

Hope this helps you...
