Q 46. During the electrochemical machining (ECM) of iron (atomic weight = 56, valency
= 2) at current of 1000 A with 90% current efficiency, the material removal rate
was observed to be 0.26 gm/s. If Titanium (atomic weight = 48, valency = 3
) is machined by the ECM process at the current of 2000 A with 90% current
efficiency, the expected material removal rate in gm/s will be
(A) 0.11
(B) 0.23
(C) 0.30
(D) 0.52
Answer: (C )
