WebSep 9, 2003 · The maximum water hammer pressure that occurs with instant valve closure can be calculated by the "Joukowasky equation" DH= c x Dv/g (SI units). DH is the pressure increase, DV is the change in pipe flow velocity, c is the wave speed (celerity), g is gravity acceleration (9.81 m/sec.sec). WebWater hammer effects can be controlled focusing efforts on reducing the magnitude of the pressure increment that can take place once the phenomenon is presented. Some of the methods try to decrease the time of closure ... named celerity, c, as it can be seen in Equation 4). (t Lcref= (4) G. Polanco et al. 292 The celerity of the pressure wave ...
Weblem of water hammer was first studied by Menabrea@3#~although Michaud is generally accorded that distinction!. Michaud @4# ex-amined the use of air chambers and safety valves for controlling water hammer. Near the turn of the nineteenth century, researchers like Weston @5#, Carpenter @6# and Frizell @7# attempted to develop WebThe celerity of pressure wave in a pipe 600m long and 1.20m in diameter is 975 m/s. Water is flowing at an initial rate of 0.85 cu.m/s. Which of the following most nearly gives the water hammer pressure at the valve if it is closed in 4 seconds?
