In an ideal gas turbine cycle with inter-cooling, reheating and regeneration as the number of compression and expansion states are increased, which of the following statements are correct?
I. The Brayton cycle reduces to Ericsson cycle.
II. The Brayton cycle reduces to Stirling cycle.
III. The cycle efficiency becomes equal to Carnot cycle efficiency.
- A. Statement I alone
- B. Statement III alone
- C. Statement I and II
- D. Statement II and III
Explanation: This question was excluded for evaluation by ISRO. However, theoretically, as the number of compression and expansion stages increases to infinity with ideal intercooling, reheating, and regeneration, the Brayton cycle approaches the Ericsson cycle, and its efficiency approaches the Carnot cycle efficiency (Statements I and III are correct).
