â ScienceWhich consequence results when excessively heating the closed Rankine cycle?
A)Turbine blade creep rupture riskâ
B)Increased condenser vacuum efficiency
C)Enhanced feedwater pump cavitation
D)Improved overall cycle thermal efficiency
ð¡ Explanation
Overheating increases material stress inside the turbine due to thermal expansion because creep deformation accelerates exponentially with temperature; therefore, blade rupture becomes likelyârather than improved vacuum/efficiencyâmainly affecting high-temperature stages.
