Which outcome affects laminar airflow when Reynold's number increases?

A)Transition to turbulent flow occurs✓

B)Viscosity effects become more dominant

C)Pressure drop decreases linearly

D)Fluid density becomes virtually negligible

💡 Explanation

Increased Reynolds number amplifies inertial forces relative to viscous forces, leading to transition to turbulence through the Kelvin-Helmholtz instability, because the system is less able to dampen disturbances. Therefore, turbulent conditions prevail, rather than laminar flow being sustained or viscosity dominating.
