Chapter 10, Problem 104RQ

Interpretation Introduction

Interpretation:

The pressure in the atmosphere and in pounds per square inch is to be calculated.

Concept Introduction:

Pressure is the ratio of force to area.

The height of the mercury column which is measured from the surface of the mercury is directly proportional to the atmospheric pressure.

The relation between density $\left(d\right)$, mass $\left(m\right)$ and volume is as:

$d=\frac{m}{V}$.

The relation between $\text{atm}$ and $\mathrm{l}{\text{b in}}^{-2}$ is as:

$1\text{ atm}=\text{14}{\text{.7 lb in}}^{-2}$.

The relation between pressure $\left(P\right)$ and area $\left(A\right)$ is as:

$P=\frac{F}{A}$

Here, $F$ is force.
