Hello,
I am looking for input into what modelling software would be best to assist me. I have been asked to confirm the effects of water hammer in a distribution main will dissipate enough to not be a concern to a typical residential service (3/4" pe) and its interior plumbing and appliances . The scenario would be an instantaneous stop during a high velocity flow (ie 10 ft/s) that creates a large surge (~170psi). The existing community has a typical operating pressure of 60psi and the homes are older and not to code. The purpose of the exercise is to determine if:
1) there is a problem with pressure surge transmitting from the main into the residential services and interior plumbing
2) is it better/more cost effective to upsize the distribution main to reduce the surge or put measures in at all residences to protect against the surge
Is there a modelling software best suited for this application?
To add to Tom's reply - I concur that HAMMER sounds like it would be a good fit. If you are familiar with WaterCAD or WaterGEMS it is also easy to use since it utilizes the same user interface (which is user friendly even if you have not used WaterCAD or WaterGEMS). On top of that we have a number of learning resources to get you up to speed quickly.
The scenario feature in HAMMER will also help you compare the different options (upsize main vs. other protection measures) to help you decide. Here are some additional resources that may help you:
