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]
- 0.75m
- 0.76m
-
3.92m
- 39.23m
The correct answer is: C
Explanation
pressure = g x density x height102000 = 10 x 2600 x height
height = 3.92m
