Clausius Inequality (Cont’d)
The system produces work δW sys as a
result of this heat transfer. Applying the
energy balance to the combined system
identified by dashed lines yields:
δW c = δQ r – dE c
Where δW c is the total work of the
combined system (δW rev + δW sys ) and
dE c is the change in the total energy of
the combined system. The cyclic device
is a reversible one.
