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
Correct Answer: Option C
Explanation
pressure = g x density x height
102000 = 10 x 2600 x height
height = 3.92m
