Chapter 9, Problem 9.40SP

Interpretation Introduction

Interpretation:

The pressure in millimetres of mercury inside a container of gas connected to a mercury open-end manometer has to be calculated.  

Concept Introduction:

Pressure of the various fluids or gases can be analyzed from the instrument known as manometer.

Pressure or Stress is the force applied perpendicular to the surface of an object per unit area.

SI derived unit of pressure is Pascal (Pa).

Millimetres of mercury

Millimeters of mercury is a manometric unit of pressure, it is well-defined as the added pressure generated by a column of mercury one millimetre high. It is represented by the symbol $\text{mmHg}$.

$\text{1}\text{mmHg=}\frac{\text{1}}{\text{760}}\text{atm}$
