Which effect occurs as dynamic viscosity increases, leading to energy dissipation in an engine's hydrodynamic bearing?

A)Fluid film thickness reduction
B)Decreased oil starvation risk
C)Increased load carrying capacity
D)Reduced bearing operating temperature

💡 Explanation

With an increase in dynamic viscosity, the viscous shear stress throughout the oil film increases imposing higher frictional losses; this promotes parasitic drag because fluid `internal friction` leads to a loss of energy to heat, generating a reduction in the oil flim thickness; therefore, there is a film thickness reduction rather than an increase affecting load with reduced thickness.
