Which outcome increases within a pipe system when Reynolds number exceeds a threshold calculated for glycerol?

A)Laminar flow instability occurrence
B)Temperature gradient stabilization
C)Cavitation erosion reduction
D)Hydraulic resistance decline

💡 Explanation

Laminar flow instability results because increased momentum overwhelms viscous damping. The Reynolds number increase signifies a transition to turbulent flow via a process often linked to the Kelvin-Helmholtz instability; therefore, instability increases rather than stability because viscous dominance is overcome contributing to turbulence.
