Which outcome occurs when a fluid transitions from a laminar regime to turbulent regime in a pipe, based strongly on Reynolds number?

A)Increased mixing and momentum transfer
B)Decreased flow rate and backpressure
C)Negligible change pressure drop rate
D)Viscosity becomes almost negligible

💡 Explanation

Turbulence increases because inertial forces begin to dominate the fluid's viscous forces, quantified by the Reynolds number; therefore, momentum transfer increases due to chaotic eddy formation, rather than viscous dominance of the fluid in laminar regimes.
