← ScienceWhich condition would destabilize laminar flow in a pump?
A)Increased fluid flow rate✓
B)Lowered fluid dynamic viscosity
C)Decreased pipe surface roughness
D)Reduced pump impeller diameter
💡 Explanation
An increased fluid flow rate can trigger turbulence because it raises the Reynolds number beyond a critical threshold; therefore transition to turbulence happens, rather than smooth flow, since inertia dominates over viscous forces.
