← ScienceWhich risk increases in a steam turbine when saturated steam experiences sudden pressure drops?
A)Erosion from increased liquid fraction✓
B)Overheating in the superheated stage
C)Decreased turbine blade vibration
D)Improved thermal efficiency occurs
💡 Explanation
Erosion risk due to increased liquid fraction rises because homogenous nucleation causes rapid condensation; therefore water droplets impact turbine blades rather than remaining superheated vapor, and avoids overheating because the transition occurs due to increased rapid condensation.
