A pipeline constructed of carbon steel failed after 3 years operation. On examination it was found that the wall thickness had been reduced by corrosion toabout half the original value. The pipeline was constructed of nominal 100 mm(4 in) schedule 40, pipe, inside diameter 102.3 mm (4.026 in), outside diameter114.3 mm (4.5 in). Estimate the rate of corrosion in ipy and mm per year.
