← ScienceWhich change results when a viscous fluid in a pipe exceeds a critical Reynolds Number?
A)Laminar flow transitions to turbulence✓
B)Fluid’s temperature linearly drops
C)Viscosity exponentially increases quickly
D)Pipe's cross-section compresses drastically
💡 Explanation
When a viscous fluid exceeds a critical Reynolds number, inertial forces overcome viscous forces; therefore, laminar flow transitions to turbulence because this instability dominates, rather than predictable temperature or shape changes.
