Question

What is the length of liquid column in a barometer tube that would support an atmospheric pressure of 102000Nm-2 if the density of the liquid is 2600kgm-3? [g = 10ms-2]

Options

A) 0.75m

B) 0.76m

C) 3.92m

D) 39.23m


The correct answer is C.

Explanation:

pressure = g x density x height

102000 = 10 x 2600 x height

height = 3.92m
