← ScienceWhich consequence results when a steam turbine operating at its maximum design temperature ingests saturated liquid water?
A)Increased thermal efficiency overall
B)Blade erosion due to cavitation✓
C)Reduced pressure within the casing
D)Superheated steam phase transition
💡 Explanation
Ingestion of saturated liquid water causes blade erosion because water droplets rapidly collapse on the turbine blades’ surface. This mechanism, called cavitation erosion, creates intense localized pressure. Turbine blades erode, therefore degrading performance, rather than improved operation; superheating prevents liquid ingestion.
