The corrosion penetration rate is illustrated by the image below. To calculate corrosion penetration rate, five essential parameters are needed and these parameters are Constant (k), Weight Loss after Corrosion (W), Density of Corroding Media (ρ), Cross-sectional Area (A) and Time (t).
The formula for calculating corrosion penetration rate:
CPR = kW/ρAt
Where:
CPR = Corrosion Penetration Rate
k = Constant
W = Weight Loss after Corrosion
ρ = Density of Corroding Media
A = Cross-sectional Area
t = Time
Let’s solve an example;
Find the corrosion penetration rate when the constant is 2, the weight loss after corrosion is 4, the density of corroding media is 6, the cross-sectional area is 12 and time is 7.
This implies that;
k = Constant = 2
W = Weight Loss after Corrosion = 4
ρ = Density of Corroding Media = 6
A = Cross-sectional Area = 12
t = Time = 7
CPR = kW/ρAt
That is, CPR = (2)(4)/(6)(12)(7)
CPR = 8/504
CPR = 0.0158
Therefore, the corrosion penetration rate is 0.0158.
