Which outcome results when lubricant flow through a narrow bearing transitions to turbulence?

A)Increased heat generation and vibration
B)Reduced oil viscosity near surfaces
C)Stable uniform temperature distribution
D)Improved load-carrying capacity overall

💡 Explanation

When lubricant flow transitions to turbulence, increased friction forces cause increased heat generation and vibration, because the increased mixing leads to viscous dissipation; therefore, increased heat and vibration results, rather than stable temperature distribution under laminar flow.
