← ScienceWhich outcome occurs when process fluid in a chemical reactor exceeds optimal Reynolds number?
A)Increased wall shear stress results✓
B)Laminar flow becomes reestablished
C)Friction losses significantly abate
D)Reduced radial thermal distribution
💡 Explanation
Increased Reynolds number promotes turbulent flow; wall shear stress increases because momentum transfer normal to the wall becomes dominant, therefore increased shear stress occurs rather than reduced mixing; laminar is incorrect.
