Chapter 6, Problem 6.27UKC

(a)

Interpretation Introduction

Interpretation:

The pressure in the pressure gauge in terms of $\text{psi}$ has to be given.

Explanation of Solution

The pressure on the pressure gauge used by the scuba divers is $\text{2600psi}\text{.}$

(b)

Interpretation Introduction

Interpretation:

The pressure on the gauge in terms of $\text{mm}\text{Hg}$ has to be given.

Answer to Problem 6.27UKC

The pressure on the gauge is $\text{1}{\text{.3×10}}^5\text{mm}\text{Hg}\text{.}$

Explanation of Solution

The pressure in $\text{psi}$ is converted to $\text{mm}\text{Hg}$ as,

  $\text{2600psi×}\frac{\text{51}\text{.715mmHg}}{\text{1}\text{psi}}\text{=134458}\text{.64mm}\text{Hg}$

The pressure on the gauge is $\text{1}{\text{.3×10}}^5\text{mm}\text{Hg}\text{.}$
