    Water hammer analysis for high pressure - low flow water network

    Dear All, I am designing a hydropneumatic tank (air vessel) to protect a water distribution network from pump trip (or power failure). The design operating point of the pumps is 150m head and only 25 lit/sec flow. This is mainly because of the hilly topography of the area and the low demands...

    Modeling air valves in pump trip- emergency startup (sewage forcemain)

    Dear All, I am designing a sewage force main which is about 5 km length and 500mm diameter. The maximum flow is 440 l/s (raw sewage) for an operating pumping head of 60m. I want to model a transient scenario for pump station power failure followed by emergency startup of pumps. I am aiming to...
