Chapter 8, Problem 8.29P

Interpretation Introduction

(a)

Interpretation:

The average cooling rate and the flow rate of brine should be calculated.

Concept introduction:

Enthalpy of a system can be calculated as,

$\Delta H=m{C}_p\Delta T$

Where, m = mass, Cp = specific heat and $\Delta T$ = change in temperature

Interpretation Introduction

(b)

Interpretation:

The ratio of heat removed to the work done and power should be estimated.

Concept introduction:

Enthalpy of a system can be calculated as,

$\Delta H=m{C}_p\Delta T$

Where, m = mass, Cp = specific heat and $\Delta T$ = change in temperature

Interpretation Introduction

(c)

Interpretation:

Why less power is that less power will be used once the dam is formed.

Concept introduction:

Enthalpy of a system can be calculated as,

$\Delta H=m{C}_p\Delta T$

Where, m = mass, Cp = specific heat and $\Delta T$ = change in temperature

Interpretation Introduction

(d)

Interpretation:

The primary radioactive species that will contaminate the ground water should be identified.

Concept introduction:

Enthalpy of a system can be calculated as,

$\Delta H=m{C}_p\Delta T$

Where, m = mass, Cp = specific heat and $\Delta T$ = change in temperature

Interpretation Introduction

(e)

Interpretation:

The source of hydrogen for the explosions should be identified.

Concept introduction:

Enthalpy of a system can be calculated as,

$\Delta H=m{C}_p\Delta T$

Where, m = mass, Cp = specific heat and $\Delta T$ = change in temperature
