Which outcome occurs when fluid velocity surpasses a pipe's threshold?

A)Transition to turbulent flow occurs✓

B)Viscosity forces become fully dominant

C)Hydrostatic pressure uniformly increases

D)Laminar flow unconditionally remains stable

💡 Explanation

Turbulent flow occurs because exceeding the critical Reynolds number initiates chaotic fluid particle behavior, a mechanism called transition to turbulence; therefore, flow changes from laminar, rather than remaining steady, as viscous forces become insufficient rather than entirely dominant under such conditions.
