Can we perform hammer for loop networks

Hi

Is to possible to model water hammer analysis for water distribution network with junctions only  and and water source is one reservoir and one pump? And if we can model it what is the steps? 

Regards

  • I concur with Craig's recommendation of taking advantage of the HAMMER training and other learning resources available.

    As for a looped network with no downstream storage - there isn't anything different to consider with this type of network compared to one with storage. After setting the appropriate demand conditions and establishing the initial conditions, you would configure the transient properties of elements (like the pump settings, pipe wave speed and transient calculation options) and compute the transient simulation.

    Note that the demands will always be considered pressure dependent during the transient simulation, so as the pressure at the demands drops when the pump shuts down, the outflow will drop accordingly. See more in this Wiki article: How are demands treated during the transient simulation in HAMMER?
