Exergy Balance Equation - an overview | ScienceDirect Topics

Exergy transfer between the system and surroundings can be done by work, mass transfer, and heat transfer. The exergy due to work transfer (Ex W) is by definition equal to the work: Ex W =W.However, if the system impinges against a moving boundary then the exergy must be diminished accordingly, thence Ex W =W–P 0 (V–V 0).The exergy associated to mass transfer (Ex m) is Ex m =m(φ).
