Which risk increases when the Carnot cycle efficiency calculations disregard frictional losses in a steam turbine?

A)Overestimated maximum possible power output
B)Underestimated condenser cooling requirements
C)Increased blade erosion from superheating
D)Premature creep failure of turbine disks

💡 Explanation

Overestimation of power output increases because the Carnot efficiency presumes ideal, reversible conditions, ignoring irreversible entropy generation during the cycle's expansion. Therefore, actual power achieved is lower, rather than predicting increased condenser needs or turbine damage stemming from frictional forces.
