Question

Quizplus · Accepted Answer

Water hammer is the impulsive force of water that is stopped too quickly. In general, the maximum recommended average velocity in a closed pipeline is 5 feet/second. When the velocity of flow within a pipeline exceeds 5 feet/second, pressure surges may develop within the pipeline when flow is stopped suddenly. The rapid change in momentum of the water causes this impulsive force.
