← ScienceWhich flow regime results when engine oil viscosity decreases?
A)Increased boundary layer separation
B)Laminar flow stabilization occurs
C)Reduced momentum diffusion effects
D)Turbulent transition Reynolds number decreases✓
💡 Explanation
A reduction in viscosity lowers the Reynolds number; therefore, turbulent flow starts sooner because the inertial forces become proportionately larger relative to viscous forces, favouring instability rather than laminar behavior.
