Chapter 16, Problem 16.6P

(a)

Interpretation Introduction

Interpretation:

The mean residence time and the variance for the non-ideal reactor are to be stated.

Concept introduction:

The mean residence time is calculated to predict the various amount of time of all the molecules in which they reside in the reactor. It is denoted by $t_m$. The mean residence time requires identifies the timing of those molecules which resides for the shorter time or for the longer time.

(b)

Interpretation Introduction

Interpretation:

The fraction of a fluid that spends $1.5\text{minutes}$ or more than $1.5\text{minutes}$ in a reactor is to be stated.

Concept introduction:

The Plug flow reactor (PFR) used for gas phase reactions and the Continuous-Stirred Tank Reactor (CSTR) mainly applied in industrial process comes under non ideal reactors which provides various residence times and fraction of fluids inside the reactors

The time of residence of fluid inside the reactor, determines the rate of conversion of the reactant or fluid, depending upon the concentration and mixing of the fluid inside the reactor.

(c)

Interpretation Introduction

Interpretation:

The fraction of a fluid that spends $2\text{minutes}$ or less than $2\text{minutes}$ in a reactor is to be stated.

Concept introduction:

The Plug flow reactor (PFR) used for gas phase reactions and the Continuous-Stirred Tank Reactor (CSTR) mainly applied in industrial process comes under non ideal reactors which provides various residence times and fraction of fluids inside the reactors

The time of residence of fluid inside the reactor, determines the rate of conversion of the reactant or fluid, depending upon the concentration and mixing of the fluid inside the reactor.

(d)

Interpretation Introduction

Interpretation:

The fraction of a fluid that spends between $1.5\text{minutes}$ and $2\text{minutes}$ in a reactor is to be stated.
