← ScienceWhich mechanism causes increased power consumption within viscous dampeners?
A)Increased fluid shear heating rate✓
B)Decreased turbulent kinetic dissipation
C)Enhanced fluid cavitation inception
D)Reduced volumetric expansion efficiency
💡 Explanation
Shear heating increases power consumption. Viscous dampeners rely on fluid friction, so increasing the shear rate elevates the fluid temperature via viscous dissipation of kinetic energy. Therefore, power consumption increases because energy must be added/removed, rather than other dissipation forms.
