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]
A
0.75m
B
0.76m
C
3.92m
D
39.23m
Verified Correct Answer: C.
Physical Principles & Numerical Solution
pressure = g x density x height
102000 = 10 x 2600 x height
height = 3.92m
