Chapter 11, Problem 27E

Interpretation Introduction

Interpretation: For the given table, pressure in different units that is in Pascal, atmospheres, millimetres of mercury, torr and pounds per square inch should be determined.

Concept Introduction: The simplest unit to measure pressure is atmospheres $\left(\text{atm}\right)$. The SI unit of pressure is Pascal $\left(\text{Pa}\right)$.Third unit to measure pressure is millimeters of mercury $\left(\text{mm Hg}\right)$.

Relation between $\text{atm}$ and $\text{torr}$ is:

$1\text{ atm}=760\text{ torr}$

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

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

Relation between $\text{atm}$ and $\text{Pa}$ is:

$1\text{ atm}=101325\text{ pa}$

Relation between $\text{psi}$ and $\text{atm}$ is:

$1\text{ psi}=\text{0}\text{.068 atm}$

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

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

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

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

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

$1\text{ in}\text{. Hg}=25.4\text{ torr}$
