Which risk increases within a lubricating system designed to reduce friction on spinning machinery as fluid viscosity decreases?

A)Increased shear stress on fluid

B)Reduced thermal stall effects overall

C)Greater adhesive system effectiveness

D)Increased boundary layer separation events✓

💡 Explanation

Decreasing fluid viscosity increases the risk of boundary layer separation because the fluid is less able to adhere to and stabilize flow along machine surfaces; therefore, turbulent eddies are more easily generated, rather than having a viscous dampened solution.
