Chapter 11, Problem 23E

Interpretation Introduction

Interpretation:

The pressure in $\text{mm Hg}$ is to be converted in $\text{atm}$, $\text{torr}$, $\text{psi}$ and $\text{Pa}$.

Concept Introduction: The simplest unit to measure pressure is atmospheres $\left(\text{atm}\right)$.

The SI unit of pressure is Pascal’s $\left(\text{Pa}\right)$.

The third unit to measure pressure is millimeters of mercury $\left(\text{mm Hg}\right)$.

Relation between $\text{torr}$ and $\text{mm Hg}$ is:

$1\text{ torr}=1\text{ mm Hg}$

Relation between $\text{atm}$ to $\text{mm Hg}$ is:

$1\text{ atm}=760\text{ mm Hg}$

Relation between $\text{mm Hg}$ to $\text{Pa}$ is:

$1\text{ mmHg}=133.322\text{ Pa}$

Relation between $\text{mm Hg}$ and $\text{psi}$ is:

$1\text{ psi}=51.715\text{ mm Hg}$
