Pressure transient is a phenomenon which can be described as waves propagated in both positive and negative magnitude. These transients are caused by rapid change in flow velocity accompanied by a change in pressure. Rapid change in flow velocity may be caused by events such as pipe bursts, sudden changes in demand, sudden pump start-ups and shut-offs, opening and closing of fire hydrants, quick closing and opening of in-line isolating valves, flushing and draining operations, fire flow, feed tank draining, and other similar events. Control of pressure transients should be one of the main concerns of the hydraulic engineer during the process of system design. Pressure transients can cause cracks and unseen small breaks in buried pipelines, pipe fittings and accessories and also can cause severe pipe ruptures and pipe bursts.
