← ScienceWhich mechanism causes reduced hydraulic efficiency in viscous fluid systems?
A)Frictional losses generate parasitic turbulence✓
B)Reduced static head increases friction
C)Cavitation erosion increases flow impedance
D)Unstable pressure differentials induce boiling
💡 Explanation
Frictional losses in viscous fluids increase turbulence through the Reynolds number threshold; the viscous frictional force is converted to turbulent kinetic energy. Therefore efficiency decreases, rather than increasing static head or inducing cavitation.
