Electrochemical machining of iron is carried out using NaCl as electrolyte. Using the data below, find the electrode feed rate?
Iron: Valency = 2, Atomic weight = 56, Density = 7840 kg/m3, Surface area = 30 × 30 mm
NaCl: Valency = 1, Atomic weight = 58.5, Density = 2160 kg/m3
Take supply voltage as 12 V and resistance of electrolyte as 1.4 × 10-2 Ω
