← ScienceWhich effect results when lubricating turbine oil contains contaminants?
A)Increased friction, accelerated component wear✓
B)Reduced thermal expansion, tighter clearances
C)Enhanced cooling, laminar boundary layer
D)Decreased system pressure, reduced vibration
💡 Explanation
Contaminants increase fluid microviscosity at contact surfaces, causing adhesive wear due to increased friction with decreased film thickness. This microabrasion increases component wear; therefore, contaminants will not enhance cooling, rather than other fluid properties remaining nominal.
