← ScienceWhich outcome results when molten glass flow exceeds a critical Reynolds number within a forming die?
A)Crystalline structure forms due cooling
B)Turbulent flow develops creating defects✓
C)Uniform laminar flow is sustained
D)Viscosity decreases dramatically preventing shaping
💡 Explanation
Turbulent flow develops because the Reynolds number exceeds the threshold, therefore disordered flow appears rather than smooth and uniform; viscosity governs the resistance and does not directly cause the described transition.
