← ScienceWhich consequence results when a turbine's Rankine cycle deviates past design threshold?
A)Increased thermal stress and fatigue✓
B)Higher efficiency from superheated steam
C)Reduced condensation within the nozzles
D)Decreased back pressure on turbine blades
💡 Explanation
Increased thermal stress and fatigue occur because excessive variance causes increased vibration. This vibrational response amplifies resonant frequencies, resulting in fatigue, therefore decreasing component lifespan, rather than optimal turbine operation, under steady conditions.
