If a valve in a pipeline is closed rapidly it will cause high-pressure waves oscillating back and forth; this is called ____

When a valve shuts quickly, the moving water has inertia and cannot stop instantly. The sudden deceleration converts the water’s kinetic energy into a rapid rise in pressure, sending a pressure wave through the pipe. This wave travels, reflects at boundaries, and can cause oscillating high-pressure surges back and forth. This hydraulic shock is known as water hammer. The idea is tied to how pressure surges propagate in a filled, elastic pipe, with the magnitude described by the relationship ΔP ≈ ρ c ΔV, where ρ is water density, c is the wave speed in the pipe, and ΔV is the change in velocity. Cavitation involves vapor bubble formation from low pressure, which is not what’s described here; backflow means flow reversal, and surge is the broader idea of transient pressure rise but the specific rapid-closure phenomenon is water hammer.
