← ScienceWhich consequence arises when exceeding the ideal regenerative heat engine's pressure limits?
A)Increased thermal radiation losses
B)Component yielding via creep rupture✓
C)Decreased compressor surge margin
D)Reduced regenerator matrix surface area
💡 Explanation
The pressure increase causes increased mechanical stress and therefore increased probability of creep rupture. Creep rupture is a stress-related failure mechanism resulting in component yielding, because exceeding operational pressure parameters rather than radiation, surge, or fouling is the direct failure cause.
