← ScienceWhich outcome results when exceeding steam turbine condensing pressure limits?
A)Water droplet blade erosion increases✓
B)Thermal energy conversion efficiency rises
C)Turbine shaft bearing life extends
D)Steam superheat phase transition is limited
💡 Explanation
Exceeding pressure limits results in increased moisture, because increased liquid mass causes impact stresses through cavitation. Therefore, accelerated blade erosion occurs, rather than efficiency rises as occurs under ideal steady-state conditions in well-designed condensers.
