Which outcome increases when expanding a closed Rankine cycle with low condenser pressure?

A)Turbine blade fatigue propagation rate
B)Feedwater pump cavitation risk margin
C)Condenser heat rejection temperature stability
D)Steam generator tube oxidation resistance

💡 Explanation

Lowering the condenser pressure in a Rankine cycle increases turbine work because it increases the pressure ratio, therefore increasing blade stress and fatigue propagation rate; rather than increasing feedwater pump cavitation, it impacts the high-pressure turbine. This mechanism is known as crack growth.
