A steel pipe is connected to a copper pipe in a galvanic corrosion couple where the electrolyte is seawater. The corrosion current density of the steel pipe is 3.2 mA/cm2. If the surface area of the steel pipe is 5 cm2, calculate the total amount of charge transferred per hour. Also, calculate the weight loss of the steel pipe per year due to galvanic corrosion, assuming the density of steel is 7.85 g/cm3.
