Which regime change occurs when Reynolds number increases?

A)Laminar flow becomes turbulent flow
B)Viscosity becomes increasingly dominant
C)Kinetic energy dissipation accelerates
D)Fluid density approaches zero isothermally

💡 Explanation

Increasing velocity causes a transition to turbulence because inertial forces become dominant; therefore, laminar flow becomes turbulent flow as the Reynolds number exceeds the critical threshold, rather than remaining stable under viscous forces.
