← TechnologyWhich outcome can result when extremely rapid valve closures occur in a long water pipeline conveying potable water?
A)Water hammer and surge pressure✓
B)Increased pipe wall strain rate
C)Turbulent energy dissipation increase
D)Uniform pressure gradient reduction
💡 Explanation
Water hammer and surge pressure result because **momentum transfer** suddenly converts kinetic energy when halting a moving fluid column. Therefore, excessive pressure spikes occur, rather than gradual pressure changes or turbulence increases. Valve closures create overpressure.
