← ScienceWhich fluid outcome occurs when lubricating turbine oil exceeds Reynolds number limits?
A)Increased heat from viscous dissipation✓
B)Decreasеd hydrodynamic bearing friction
C)Enhanced laminar boundary layer stability
D)Improved centrifugal pump cavitation
💡 Explanation
Turbulence develops because increased velocity enhances inertial forces relative to viscous damping; increased Reynolds number indicates this. Therefore viscous dissipation occurs via energy transfer to turbulent eddies, rather than reduced friction arising from less viscous flow.
