Input information:

water hammer pressure with slow closure |  \npressure difference | 20 atm  (atmospheres)\nupstream pipe length | 2 feet\nvalve closing time | 5 seconds\ninlet pressure | 400 Pa  (pascals)


Result:

flow velocity of fluid | 3.199 km\/s  (kilometers per second)\n= 7156 mph  (miles per hour)\n= 11516 km\/h  (kilometers per hour)


Equation:

DeltaP = (0.07 s^2lbf\/(ft^2in^2) v L)\/t + P |  \nv | flow velocity of fluid\nDeltaP | pressure difference\nL | upstream pipe length\nt | valve closing time\nP | inlet pressure\nlbf | pound-force (~~ 9.807 lb m\/s^2)\n(assuming an incompressible fluid)
