Calculate the corrosion rate of a steel rod when it is placed in a galvanic coupling with a copper strip at 25°C. The initial weight of the steel rod was 28.6 g and it lost 0.48 g in weight after 24 hours of exposure. The area of the steel rod in contact with the electrolyte solution is 3.14 cm² and the electrode potential of the copper strip is +0.34V while the electrode potential of the steel rod is -0.44V. Using Faraday’s law of electrolysis, determine the corrosion rate of the steel rod in mmpy (mils per year).
