Relation between venting speed and pipe pressure, water moving speed and pipe pressure

Accidents of exploding pipe frequently occurred in water feeding system of cities, result in terrible effectivation on industry and residents' life. Under the investigation of the accidents , it was discovered that most of them belonged to water-hammer imputing to bad vents. However, that was not attached in rationalize of choosing and installing vent valves. So we simulate enviroment of vent valve'working condition in practical engineering and according to expriment data , analyze relation between venting speed and pipe pressure, water moving speed and pipe pressure. We hope it's helpful to rationalize of choosing vent valves.
