and aluminum are given in the table below.
nore overpotentials, and assume that current efficiency is 100% for both the
workpiece materials. Under identical conditions, if the material removal rate (MRR)
of copper is 100 mg/s, the MRR of aluminum will be ________________ mg/s
(round-off to two decimal places).
Correct : 166.67
