← ScienceWhich outcome results when laminar flow through a syringe transitions?
A)Increased fluid pressure fluctuation occurs✓
B)Viscosity effects become negligible there
C)Reynolds number approaches zero quickly
D)Flow velocity becomes virtually constant
💡 Explanation
Increased fluid pressure fluctuation occurs, because the laminar flow transitions to turbulent flow via loss of stability; this causes increased momentum transfer, resulting in more collisions associated with viscous stresses. Therefore, fluid pressure increases rather than becoming negligible, in contrast to stable state.
