Chapter 6, Problem 6.25P

Interpretation Introduction

(a)

Interpretation:

Estimate whether it is possible for the average gas-phase composition in the tank to be within the explosive limits at any time. Explain you answer.

Concept introduction:

The Ideal Gas Law is defined as,

$PV=nRT$

Where, the volume (V) occupied by ‘n’ moles of any gas has a pressure (P) at temperature (T) in Kelvin and ‘R’ = Gas constant

Interpretation Introduction

(b)

Interpretation:

The temperature at which the gas tank to be at lower explosive limit should be determined.

Concept introduction:

The Ideal Gas Law is defined as,

$PV=nRT$

Where, the volume (V) occupied by ‘n’ moles of any gas has a pressure (P) at temperature (T) in Kelvin and ‘R’ = Gas constant

Antoine equation

Antoine equations describe the relationship between vapor pressure and temperature for pure components. This is a semi-empirical relationship.

Interpretation Introduction

(c)

Interpretation:

Why is the tank purged thoroughly with steam after being drained should be explained.
