The diagram T-s in Fig. 15b also shows the corresponding Carnot Cycle 1′-3-4-5-1′. Clearly, one can see that the Carnot cycle has a higher thermal efficiency than the simple Rankine cycle by simply reasoning that heat is delivered to the Rankine cycle at an average temperature (between T 2 and T H) lower than the one for the Carnot cycle (T H).
