Q.
While removing material from iron (atomic weight = 56, valency = 2 and density = 7.8 g/cc by electrochemical machining, a metal removal rate of 2 cc/min is desired. The current (in A) required for achieving this material removal rate is
Q.
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 cc/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
