← ScienceWhich outcome results when laminar flow transitions to turbulence?
A)Increased drag force on submerged objects✓
B)Decreased pipe friction losses significantly
C)Enhanced heat transfer across streamlines
D)Reduced mixing of different fluid layers
💡 Explanation
Increased drag occurs because transitioning from laminar to turbulent flow involves increased momentum transfer due to small chaotic changes known as eddies; this increases the Reynolds number toward and beyond the critical point. Therefore, drag increases rather than reduces friction losses because laminar flow remains more streamlined.
