← ScienceWhich outcome results when laminar flow transitions via the critical Reynolds number in a pipe?
A)Increased pressure due to fluid deceleration
B)Fully developed turbulent flow is established✓
C)Decreased overall friction losses occur
D)A stable, predictable flow streamlines result
💡 Explanation
Turbulent flow develops because exceeding the critical Reynolds number triggers flow instabilities that amplify disturbances via the mechanism of energy cascade. Therefore, the flow becomes fully turbulent rather than remaining laminar and energy is dissipated as turbulence eddies form.
