Chapter 23, Problem 23.34P

Interpretation Introduction

Interpretation:

The plate height depend on linear velocity, not volume flow rate reason for this observation has to be given.

Concept introduction:

Van Deemter equation:

This equation explains how the plate height is affected by the column and flow rate

$\begin{array}{l}\text{H}\approx \text{A}\text{+}\text{}\frac{\text{B}}{{\text{u}}_{\text{x}}}\text{+}{\text{Cu}}_{\text{x}}\\ \text{Where,}\\ \text{H}\text{-}\text{plate}\text{height}\\ \text{A,}\text{B,}\text{C}\text{-}\text{constants}\text{for}\text{a}\text{given}\text{column}\\ {\text{u}}_{\text{x}}\text{-}\text{linear}\text{velocity}\end{array}$
