Chapter 17, Problem 13QAP

(a)

To determine

To demonstrate:

The CPR is related to the corrosion current density $i\left(\text{A}/{\text{cm}}^{\text{2}}\right)$ through the expression $\text{CPR}=\frac{KAi}{n\rho }$

(b)

To determine

The value of the constant $K$ for the CPR in $\text{mpy}$ and $i$ in $\text{μA}/{\text{cm}}^{\text{2}}\left({10}^{-6}\text{A}/{\text{cm}}^{\text{2}}\right)$.
