← ScienceWhich outcome occurs when cryogenic liquid helium's flow through a narrow pipe exceeds the Reynolds number limit?
A)Transition to turbulent flow regime✓
B)Increased heat transfer efficiency
C)Formation of quantized vortices ceases
D)Superfluidity spontaneously becomes established
💡 Explanation
Exceeding the Reynolds number causes a transition from laminar to turbulent flow because inertial forces overwhelm viscous damping; therefore, the flow becomes disordered, rather than staying smooth; superfluidity depends on temperature, not Reynolds.
