Which consequence results if an industrial Rankine vapor cycle's condenser is undersized?

💡 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.
