← ScienceWhich risk increases when a turbine's condensed steam re-enters at saturation?
A)Cavitation erodes the impeller blades✓
B)Excessive thermal loading on pipelines
C)Lubricant viscosity increases steadily
D)Generator output suffers field quenching
💡 Explanation
Cavitation damage increases because the phase change from liquid to vapor causes rapid bubble formation and collapse within the pump, which leads to pitting; therefore, cavitation becomes more likely, rather than excess thermal stress or quenching, which require different temperature gradients and magnetic fields.
