Chapter 1, Problem 1.27P

Interpretation Introduction

(a)

Interpretation:

The order of the three energy sources with respect to energy cost in $. GJ-1 should be determined.

Concept Introduction:

The cost of the three energy sources with respect to different units is given, these units can be converted into $. GJ-1 by using the following conversions.

$1\text{ ton}=\text{907}\text{.185 kg}$

$1\text{ MJ}={\text{10}}^6\text{ J}$

$1\text{ GJ}={\text{10}}^9\text{ J}$

And,

$1\text{gal}=\text{0}{\text{.00378541 m}}^3$

Interpretation Introduction

(b)

The large disparity in the numerical results of part (a) should be explained. The advantages and disadvantages of the three energy sources should be discussed.
