6. A sheet of carbon steel one meter wide by three meter long has lost 40 g with a current density of 1.69 x 10+ A/cm over the past six months. Suppose that only one face of the metal is exposed to corrosive media. Determine the corrosion rate in: (a) mmpy (Millimeter per year) (b) mdd (milligrams per decimeter per day) (c) ipy (inches per year) mmpy (millimeter per year) D= 7.8 g/cm M=55.84 g/mol F = 96500 C/mol
