Chapter 8, Problem 8.66P

Interpretation Introduction

(a)

Interpretation:

Draw the process flow chart and prove that given information is enough to determine the unknowns.

Concept introduction:

Mass fraction is defined as the ratio of one component to the total mixture as,

$x=\frac{n_A}{n_A+n_B}$

Where, x = mass fraction, $n_{A}and{n}_B$ are the components of the substance.

Interpretation Introduction

(b)

Interpretation:

Calculate the fraction of the river flow that must be diverted to the plant and the percentage of the cooling water that evaporates.

Concept introduction:

Mass fraction is defined as the ratio of one component to the total mixture as,

$x=\frac{n_A}{n_A+n_B}$

Where, x = mass fraction, $n_{A}and{n}_B$ are the components of the substance.

Interpretation Introduction

(c)

Interpretation:

Write an expression for the enthalpy change neglected.

Concept introduction:

Mass fraction is defined as the ratio of one component to the total mixture as,

$x=\frac{n_A}{n_A+n_B}$

Where, x = mass fraction, $n_{A}and{n}_B$ are the components of the substance.
