← ScienceWhich outcome happens when pumping viscous fluid if Reynolds number increases?
A)Increased energy loss turbulent eddies✓
B)Decreased wall shear stress effects
C)Reduced pump cavitation probability greatly
D)Enhanced system laminar flow stability
💡 Explanation
An increased Reynolds number signifies a transition towards turbulence; because inertial forces dominate, turbulent eddies appear causing energy dissipation. Therefore, energy loss increases, rather than the stability, which decreases as viscosity dampens, while the pump becomes harder to control.
