The wave velocity and surge pressure that result from abrupt changes in the veloc- ity of a column of water moving through a restrained pipe may be calculated using the following equations: a = K r (Eg F-2) 1 + Kd E PE (t PEi+ t PEo ) + E AL(t AL ) P s = rv o a (Eq F-3) Where: a = wave velocity, ft/sec (m/sec) K = bulk modulus of water 294,000 lb/in. 2(2,100 MPa) Copyright 2016 American Water Works Association.
