← ScienceWhich risk increases when exceeding Carnot cycle high fluid pressure?
A)Valve cavitation erodes impeller blades
B)Compressor motor windings overheat quickly
C)Expansion turbine tip speed exceeds limits
D)Regenerator matrix fractures under stress✓
💡 Explanation
High pressure increases stress, therefore microfractures propagate initiating the mechanism creep. Damage accumulates because exceeding pressure limitations causes regenerator material failure rather than failures in other components occurring at lower pressures.
