1.    A sheet of carbon steel one meter wide by three meter long has lost 40 g with a current density of 1.69 x 10-4 A/cm2 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 decimeter2 per day)

  (c) ipy (inches per year)                                                                                                

 mmpy (millimeter per year)

D = 7.8 g/cm3

M = 55.84 g/mol


F  = 96500 C/mol
