The ratio of theoretical power that must be supplied to operate the pump to the actual power delivered to the pump is-
Mechanical efficiency
In the context of defining mechanical efficiency, this refers to the power input to the pump's impeller, which is the power transferred from the shaft to the rotating fluid before any mechanical losses occur. Therefore, the ratio of the theoretical power that must be supplied to operate the pump (power input to impeller) to the actual power delivered to the pump (power input to shaft) is the mechanical efficiency.
