Chapter 2, Problem 2.50P

Interpretation Introduction

(a)

Interpretation:

The plot that would yield a straight line and helps in determining the parameters a and b should be determined.

Concept introduction:

A hazardous waste needed to be disposed. So, the solution of this waste is pumped into a storage tank. Then, the solution subjected to chemical treatment. Due to the chemical treatment, the concentration (C) of the decomposing waste has been reported to vary with time (t) according to the formula.

$C=1/\left(a+bt\right)$

Where a and b are constants.

Interpretation Introduction

(b)

Interpretation:

The value of a and b should be estimated using graphics software. The graph of C vs t to show both measured and predicted values should be plotted.

Concept introduction:

A hazardous waste needed to be disposed. So the solution of this waste is pumped into a storage tank. Then, the solution subjected to chemical treatment. Due to the chemical treatment, the concentration (C) of the decomposing waste has been reported to vary with time (t) according to the formula.

$C=1/\left(a+bt\right)$

Where a and b are constants.

Interpretation Introduction

(c)

Interpretation:

Using answers in part (b), the initial concentration of the waste in the tank and the time required for C to reach its discharge level should be calculated.

Interpretation Introduction

(d)

Interpretation:

The little confidence in the time estimated in part (c) should be explained.

(e)

Interpretation:

The potential problems with the waste disposal method should be calculated.
