Which mechanism decreases the performance of steam turbines at elevated backpressures?

💡 Explanation

Increased backpressure elevates the saturation temperature; therefore increased exhaust moisture results from reduced last-stage expansion because the phase change occurs earlier; turbine blade erosion increases rather than superheating the steam.
