Chapter 5, Problem 5.17NP

Interpretation Introduction

Interpretation:

The factor by which it is more expensive to extract the same amount of heat from the freezer than from the refrigerator under the given temperature conditions needs to be calculated

Concept Introduction:

The coefficient of performance (η) of a Carnot refrigerator is a function of the reservoir temperatures and can be expressed as:

  $\text{η = }\frac{{\text{T}}_{\text{cold}}}{{\text{T}}_{\text{hot}}-{\text{T}}_{\text{cold}}}\text{ ------(1)}$ 0
