The basic Rankine cycle is presented in terms of temperature and entropy change in Figure 10. . The entropy generation analysis is an approach to optimize the performance of different thermal systems by investigating the related irreversibilities of the system. This is because the work done by or on the system and the heat added to or removed from the system can be visualized on the T-s diagram.
