A steel pipe is in contact with a copper pipe in a galvanic couple, with the steel pipe acting as the anode. The corrosion current density of the steel pipe in the couple is 0.008 mA/cm². Determine the rate of corrosion of the steel pipe, assuming that the density of steel is 7.8 g/cm³ and the thickness of the pipe is 2.5 mm. Also, calculate the time taken for the pipe to corrode completely, assuming an initial mass of 5 kg.
