Chapter 5 – Problem 5.7

5.7 Surge anticipation valves (SAV) may be used as protection devices to control extreme high pressures that occur following a pump trip event on long pumping mains. Consider a rising main pipeline system as shown in the following figure and the associated envelope of high and low surge pressures during a pump trip event without any surge protection device at the pump station. The graph to the right of the pipeline profile shows the pressure variation at the pump discharge following the pump trip event (again, without any protection device at the pump station). Explain why a surge anticipation valve-based protection may not be a good idea for this pipeline system.
