← ScienceWhich risk increases when the Carnot cycle's isothermal expansion approaches infinite rate in a turbine?
A)Kinetic energy output plateaus abruptly
B)Turbine blade yielding by creep increases✓
C)Thermal efficiency suddenly achieves ideality
D)Internal stages experience total blockage
💡 Explanation
Turbine blade yielding by creep increases because isothermal processes require extended time, therefore, attempting infinite rate concentrates excessive stress, resulting in failure by hot creep, rather than constant power operation expected.
