Chapter 13, Problem 34A

Interpretation Introduction

Interpretation: The pressure in the atm is to be calculated.

Concept introduction:

The force perpendicularly exerted on the surface of an object divided by the region or area over which it is dispersed is known as pressure. The pressure is measured in various units. The units in which pressure is measured are:

• Pascal
• $\text{N}/{\text{m}}^{\text{2}}$
• mmHg
• atm
• Torr

Answer to Problem 34A

  $\text{16}\text{.34 atm}$

Explanation of Solution

The given pressure is $1656\text{ kPa}$

The relation between atm and kPa is as shown,

  $1\text{ atm}=101.325\text{ kPa}$

Calculate the pressure in atm as follows:

  $\begin{array}{c}1656\text{ kPa}=1656\bcancel{\text{kPa}}\times \frac{1\text{ atm}}{101.325\bcancel{\text{kPa}}}\\ =\text{16}\text{.34 atm}\end{array}$

Thus, pressure in atm is $\text{16}\text{.34 atm}$ .
