Chapter 6, Problem 6.21P

Interpretation Introduction

(a)

Interpretation:

Calculate the daily rate which octane is used.

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:

Calculate the variation in absolute pressure at the bottom of tank

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

(c)

Interpretation:

Calculate the amount of octane lost to the atmosphere.

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

(d)

Interpretation:

Why is nitrogen used in the vapor space instead of air?

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

(e)

Interpretation:

Suggest a method to recover octane from the gas stream.

Concept introduction:

The Ideal Gas Law is defined as,

$PV=nRT$
