Which limitation results when a closed Rankine cycle operates without superheating?

A)Lower overall thermal efficiency
B)Increased turbine blade erosion
C)Higher condenser pressure required
D)Reduced feedwater pump performance

💡 Explanation

Increased turbine blade erosion emerges due to moisture. Wet steam exists because *isentropic expansion* leads to water droplets impacting the turbine's last stages; therefore erosion increases, rather than the pressure or efficiency being chiefly impacted under these specific thermodynamic circumstances.
