← ScienceWhich outcome is amplified because of increased hydraulic viscosity?
A)Increased vortex shedding frequency✓
B)Reduced flow induced vibration
C)Higher cavitation inception number
D)Diminished pipe wall erosion
💡 Explanation
Increased viscosity causes greater fluid resistance and turbulent energy dissipation leading to increased vortex shedding frequency, because momentum diffusion grows along with turbulent eddy sizes. Hence vortex frequencies rise, rather than diminish with dampening viscosity affects instead.
