← ScienceWhich outcome results when laminar flow transitions beyond a critical Reynolds number?
A)Increased convective heat transfer occurs
B)Increased skin friction drag develops✓
C)Pressure drop across a pipe decreases
D)Efficiency of mixing drops extremely
💡 Explanation
Turbulent flow is characterized by chaotic changes in pressure and velocity because momentum diffusion increases sharply due to eddy formation known as turbulence transition; therefore increased friction drag occurs, rather than decreased, because laminar flow converts to turbulent flow.
