Chapter 9, Problem 9.38SP

Interpretation Introduction

Interpretation:

The atmospheric pressure at the top of Pikes Peak in Colorado is approximately $\text{480}\text{mmHg}$ and the value of Pikes Peak in Pascal’s 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 $\text{mmHg}$.

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