← ScienceWhich outcome occurs when exceeding the adiabatic efficiency threshold in a turbine?
A)Reduced power output from irreversibilities✓
B)Increased blade fatigue from resonance
C)Elevated outlet temperature, approaching isothermality
D)Decreased exergy destruction minimum is reached
💡 Explanation
Exceeding adiabatic efficiency prompts increased entropy generation through irreversibilities lowering real-world output because the expansion becomes less adiabatic. That reduces delivered work rather than initiating blade fatigue like resonance; increased temperature follows decreased efficiency.
