Chapter 4, Problem 4.92P

Interpretation Introduction

(a)

Interpretation:

Draw the flow chart and perform the degree of freedom analysis.

Concept introduction:

The degree of freedom is given by the equation as,

${\text{n}}_{\text{df}}{\text{=n}}_{\text{unknowns}}{\text{-n}}_{\text{indep}\text{eqns}}$

Where, ${\text{n}}_{\text{unknowns}}$ = number of unknowns and ${\text{n}}_{\text{indep}\text{eqns}}$ = number of independent equations

Interpretation Introduction

(b)

Interpretation:

Prove that reported percentages are not correct.

Concept introduction:

The degree of freedom is given by the equation as,

$n_{df}=n_{unknowns}-n_{indepeqns}$

Where, $n_{unknowns}$ = number of unknowns and $n_{indepeqns}$ = number of independent equations

Interpretation Introduction

(c)

Interpretation:

Prove that results are correct and calculate the percentage air fed and fractional conversion of pentane.

Concept introduction:

The degree of freedom is given by the equation as,

$n_{df}=n_{unknowns}-n_{indepeqns}$

Where, $n_{unknowns}$ = number of unknowns and $n_{indepeqns}$ = number of independent equations
