The assembly efficiency if the theoretical minimum number of parts for a geared water pump is three and the total assembly time 116 seconds is 7.79 %
ηassembly = Nmin ta / t
ηassembly = Assembly efficiency
Nmin = Minimum number of parts to assemble
ta = Basic assembly time for one part
t = Total time
t = 116 s
ta = 3 s
Nmin = 3
ηassembly = 3 * 3 / 116
ηassembly = 0.077856
ηassembly = 7.79 %
Assembly is a step in manufacturing process in which different parts gets assembled to make a working product. Efficiency is basically how much energy can be conserved.
Therefore, the assembly efficiency is 7.79 %
