Chapter 18, Problem 18.15P

Interpretation Introduction

Interpretation:

Time required prior to leakage of pipe under given conditions should be determined.

Concept Introduction:

• Electroplating is a process of generating electric current for the purpose of protective or decorative coating on material.
• Plating is done by either mechanical or chemical processing.
• Electroplating consist of anode, cathode, electrolyte.
• Time required for plating before exposing is calculated by,

  $t=\frac{wnF}{IM}$

Where,

w = mass of substance/metal

n = charge of metal ions

F = faraday's constant

I = current in the cell

M = atomic mass of metal
