Chapter 19, Problem 19.9VP

Interpretation Introduction

Interpretation: The reason of most of the corrosion on the metal pilings most at the waterline and less at heights above and below the waterline is to be analyzed.

Concept introduction: Corrosion is an electrochemical process. The presence of a little amount of electrolyte upon unprotected metal surface could cause electrons to flow, that leads to corrosion. Most commonly serve electrolyte is water in water vapor.

To determine: The reason due to which, most of the corrosion on the metal pilings most at the waterline and less at heights above and below the waterline.
