Entropy Balance

Thermodynamics

As per the entropy concept, the entropy change of any system is more than the entropy transfer by an amount equal to the entropy generated during the process.

ENTROPY BALANCE

As per the entropy concept, the entropy change of any system is more than the entropy transfer by an amount equal to the entropy generated during the process. It makes the imbalance between entropy change of the system and entropy transfer from the system. The entropy balance equation for any system can be expressed as


This entropy balance equation (3.16) can be applied to any system undergoing any thermodynamic process.

For unit mass, it can be written as


The entropy balance can be stated that the entropy generation during the process is the sum of the change in entropy of the system and change in entropy of the surrounding.
