Chapter 9, Problem 9.4P
Interpretation Introduction

(a)

Interpretation:

The pressure at states 1, 2, 3, and 4 should be determined.

Concept Introduction:

As per the 2nd rule of thermodynamics, work is needed to transfer heat from a cold region to a hot region. A refrigeration system transfers the heat from the heat source (icebox) to the surrounding (kitchen). The operating mechanism of a refrigeration cycle was mathematically illustrated by Carnot as a heat engine in the year 1824.

Interpretation Introduction

(b)

Interpretation:

The quality xυ at states at 3 and 4 should be determined.

Concept Introduction:

The operating mechanism of a refrigeration cycle was mathematically illustrated by Carnot as a heat engine in the year 1824.

Interpretation Introduction

(c)

Interpretation:

The heat addition per kg of fluid should be determined.

Interpretation Introduction

(d)

Interpretation:

The heat rejection per kg of fluid should be determined.

Concept Introduction:

As per the 2nd rule of thermodynamics, work is needed to transfer heat from a cold region to a hot region.

Interpretation Introduction

(e)

Interpretation:

The mechanical power per kg of fluid for each of the four steps should be determined.

Concept Introduction:

As per the 2nd rule of thermodynamics, work is needed to transfer heat from a cold region to a hot region. A refrigeration system transfers the heat from the heat source (icebox) to the surrounding (kitchen). The operating mechanism of a refrigeration cycle was mathematically illustrated by Carnot as a heat engine in the year 1824.

Interpretation Introduction

(f)

Interpretation:

The coefficient of performance ? for the cycle should be determined.
