Chapter 13, Problem 13.89P

Interpretation Introduction

Interpretation:

Effective force in pounds required to pull the two hemispheres apart has to be calculated.

Concept Introduction:

The expression to calculate force that holds the two hemispheres together is as follows:

  $F=P_{\text{atm}}{A}_0$

Here,

$P_{\text{atm}}$ isexternal pressure.

$A_0$ denotes cross sectional area.

The relation between $\text{bar}$ and $\text{Pa}$ is as follows:

  $\text{1 bar}={10}^5\text{ Pa}$

The conversion factor to convert $\text{atm}$ to $\text{bar}$ is as follows:

  $1\text{ atm}=1.01325\text{ bar}$
