Chapter 25, Problem 25.11P

a)

Interpretation Introduction

Interpretation:

A peak has to be sketched with an asymmetry of 1.8.

Concept Introduction:

Foley-Dorsey equation:

Foley-Dorsey equation is used to estimate the number of plates for tailed peaks and the equation is given below,

$\text{N}\approx \frac{\text{41}\text{.7}{\left({\text{t}}_{\text{r}}{\text{/w}}_{\text{0}\text{.1}}\right)}^{\text{2}}}{\left(\text{B/A}\right)\text{+1}\text{.25}}$

Where ${\text{w}}_{\text{0}\text{.1}}\text{=A+B}$ that is width at $\text{1/10}$ th of height. The quantites A and B are used to estimate the asymmetry factor B/A

b)

Interpretation Introduction

Interpretation:

The way to correct the asymmetry has to be given.
