Which outcome occurs when the working fluid in a turbine's closed Rankine cycle superheats?

A)Increased cycle thermal efficiency
B)Reduced system operating pressure
C)Decreased turbine blade erosion
D)Lower condenser heat rejection rate

💡 Explanation

Superheating increases the average temperature at which heat is added during conversion, which leads to a greater thermal efficiency due to Carnots' principle. Therefore the cycle thermal efficency increases, rather than lower pressures that arise from increased volume.
