Interpretation Introduction

Interpretation:

Height of the oil column (in meters) in the barometer has to be calculated.

Concept Introduction:

Density of a liquid can be determined using a mercury barometer as follow,

  ${\text{d}}_{\text{Hg}}{\text{h}}_{\text{Hg}}{\text{ = d}}_{liq}{\text{h}}_{liq}$

Where d is the density and h is the height of the liquid in barometer.

Unit conversion:

  $\begin{array}{l}1\text{ m = 1000 mm}\\ \\ 1\text{ atm = 760 Torr = 760}\text{mm}\text{Hg}\end{array}$
