Question
? In Electro Chemical machining processes of Iron, a MRR of
2cm3/min was desired. Determine the amount of current required
for this process(Take atomic weight of iron =56gr, valiancy=2 and
density =7.8 gr/cm3)​

Answer 1

Given:

Metal removal rate = 2 cm³/min

Atomic weight of iron = 56 g

Valency = 2

Density of iron = 7.8 g/cm³

To find:

The amount of current required for the process

Calculation:

Metal removal rate is given by the relation

     $M.R.R=\frac{IA_{t}}{fvp}$

By substituting the given values in the above relation:

      $2=\frac{I\times56}{1609\times2\times 7.8} \\ \\I=\frac{1609\times2\times 7.8\times 2}{56}\\ \\ I = 896.44\ A$

Final answer:

The amount of current required for the process is 896.44 A
