← ScienceWhich outcome results in turbine blades when encountering superheated steam?
A)Decreased turbine efficiency due to erosion✓
B)Uniformity of turbine blade metal deposition
C)Improved heat transfer in all blades
D)Reduction of blade failures across rotors
💡 Explanation
Erosion occurs because droplet formation accelerates impact speed, causing cavitation. Droplets impinge due to repeated Kinetic Energy transfer, wearing surfaces rather than uniform condensation. This leads to efficiency loss therefore erosion, rather than blade integrity.
