← ScienceWhich outcome decreases hydraulic efficiency within a centrifugal slurry pump, when handling solid-liquid mixtures near a critical limit affecting the Reynolds number?
A)Increased frictional pressure drop✓
B)Enhanced laminar boundary layer
C)Diminished impeller blade erosion
D)Improved fluid-structure interaction
💡 Explanation
Increased frictional pressure results, caused by flow transition; the *transition to turbulence* because solids prevent a consistent laminar flow and therefore increases friction dramatically, rather than the flow remaining laminar, affecting pump efficiency.
