← ScienceWhich outcome accelerates when oil viscosity decreases inside hydrodynamic machinery?
A)Increased bearing material cavitation erosions.✓
B)Stabilized fluidic pressure amplifications
C)Improved boundary layer laminarity
D)Reduced mechanical component oxidation
💡 Explanation
Decreased viscosity reduces the oil film thickness in hydrodynamic machinery. This invokes increased boundary contact and adhering bubble implosions from cavitation, therefore erosion is accelerated rather than reduced oxidation arising from less component contact.
