Which efficiency decrease results when turbine preheating diminishes?

💡 Explanation

Diminished turbine preheating reduces cycle efficiency due to decreased average temperature during heat addition; therefore, thermal cycle energy is lessened because the available exergy is decreased, rather than more favorable alternative thermal efficiencies.
