← ScienceWhich outcome occurs when a closed, saturated steam system used for power generation contains a sudden nucleation point?
A)Pressure drop and flashing occurs✓
B)Superheating decreases overall efficiency
C)Turbine blade erosion is minimized
D)Refrigerant subcooling increases thermal stability
💡 Explanation
Rapid phase change (vapor to liquid) leads to a sudden pressure drop because of steam condensation via homogeneous nucleation; therefore, flashing can occur, rather than maintaining equilibrium; superheating and blade erosion are more gradual processes.
