← TechnologyWhich mechanism causes fluid hammer pressure spikes when rapidly closing a hydraulic actuator's control valve, potentially damaging pipeline components?
A)Fluid deceleration momentum amplification✓
B)Viscous damping energy dissipation
C)Turbulent boundary layer separation
D)Laminar flow profile stabilization
💡 Explanation
Fluid hammer arises because the fluid's kinetic energy converts to pressure upon sudden valve closure due to fluid deceleration momentum amplification. Therefore, there's a strong pressure surge rather than gradual pressure equalization via damping or flow stabilization.
