← ScienceWhich consequence results when Newtonian fluid viscosity increases?
A)Increased laminar flow stability
B)Reduced turbulent boundary layer thickness
C)Higher critical Reynolds number initiation✓
D)Decreased energy dissipation during mixing
💡 Explanation
Increased viscosity raises resistance to deformation, inhibiting the onset of turbulence via increased viscous damping. Therefore, the resulting higher critical Reynolds number indicates a postponed transition point, rather than earlier ones that occur with greater fluid instability.
