If Plant A has $T_H = 900 ext{ K}$ and Plant B has $T_H = 1200 ext{ K}$ (both rejecting at $T_C = 300 ext{ K}$), what does this illustrate about efficiency gains?
Answer
It shows that even incremental increases in operating temperature ($T_H$) yield substantial theoretical gains in efficiency.
Plant A's efficiency is $\approx 66.7\%$, while Plant B's is $75\%$. This substantial jump resulting from raising $T_H$ demonstrates the significant theoretical gain achieved by increasing the operating temperature.
