Chapter 1, Problem 1.54QP

Interpretation Introduction

Interpretation:

For the given data, the volume of air per breath should be determined.

Concept Introduction: 

• Volume is the ratio of mass to density and its SI unit is ${\text{m}}^{\text{3}}$.

$Volume=\frac{Mass}{Density}$

• Conversion formula:

  $\begin{array}{l}1\text{gallon}\text{=}\text{3}\text{.79}\text{L}\\ \text{1}\text{mL}\text{=}\text{0}\text{.001L}\\ \text{1}\text{mL}\text{=}\text{1}\text{g}\end{array}$

• $Thickness=\frac{Volume}{area}$

  Given:

• Adult needs 240mL of pure oxygen per minute and breath 12 times every minute.
• Inhale air contain 20 percent oxygen by volume and exhale air 16 percent.
• The volume of inhale air is equal to volume of exhale air.
