← ScienceWhich consequence results when insufficient lubrication occurs in a turbine engine?
A)Increased parasitic drag and fuel consumption
B)Rapid component wear by adhesive wear✓
C)Decreased thermal efficiency turbine
D)Elevated exhaust emissions pollution
💡 Explanation
Insufficient lubrication causes increased dry contact between rotating pieces. This results by increased Adhesive wear, thus increasing component wear, because asperity tips shear, removing material, therefore component degradation accelerates rapidly, leading to catastrophic failure rather than reduced thermal efficiency.
