Chapter 10, Problem 10.17P

Interpretation Introduction

(a)

Interpretation:

A differential balance on the tracer should be determined along with the initial conditions.

Concept introduction:

The Mass balance of tracer is the net accumulation (A) in the tank which is basically the

difference between the input (in) and output of the tank (out). It is given as follows:

$A=in-out$

Interpretation Introduction

(b)

Interpretation:

Prove the given expression.

Concept introduction:

The Mass balance of tracer is the net accumulation (A) in the tank which is basically the

difference between the input (in) and output of the tank (out). It is given as follows:

$A=in-out$

Interpretation Introduction

(c)

Interpretation:

Verify graphically that the tank is functioning as a perfect mixer and calculate the effective volume from the slope of your plot.

Concept introduction:

The Mass balance of tracer is the net accumulation (A) in the tank which is basically the

difference between the input (in) and output of the tank (out). It is given as follows:

$A=in-out$

Interpretation Introduction

(d)

Interpretation:

The drawback of radiotracers and the half-life of the radioactive tracer should be explained.

Concept introduction:

The Mass balance of tracer is the net accumulation (A) in the tank which is basically the

difference between the input (in) and output of the tank (out). It is given as follows:

$A=in-out$
