Mechanical efficiency is used to calculate shaft power. Shaft power is the ratio of shaft work to mechanical efficiency.
Usage
The mechanical efficiency is 100%, by default. You can change this value if desired.
Alternatively, instead of entering a value for mechanical efficiency, the numeric value may be referenced using the Define system relative to any available unit operation or stream parameter calculated elsewhere in the simulation. See Pump Parameters Available for Cross-Referencing for more details.
