← ScienceWhich consequence results if an industrial Rankine vapor cycle's condenser is undersized?
A)Decreased turbine blade fatigue rate
B)Increased system thermal efficiency
C)Reduced cycle steam mass flow
D)Elevated turbine back pressure✓
💡 Explanation
Elevated turbine back pressure results from an undersized condenser because the heat rejection capability is reduced, causing increased pressure via the Clausius-Clapeyron relation, therefore limiting expansion rather than decreasing mass flow or improving efficiency.
