Which outcome occurs when rapid pipe enlargement causes turbulence?

A)Increased pressure drop
B)Decreased wall shear stress
C)Decreased mixing efficiency
D)Increased pump cavitation

💡 Explanation

Increased pressure drop occurs because flow separation creates chaotic eddies; therefore, kinetic energy dissipates as heat via increased viscous forces with turbulence, rather than streamlined flow with minimized losses at lower Reynolds numbers.
