Thanks Jim and Scot, KY pipe is actually what we are going to use. I am learning it now and we have a couple of experienced users to help me through the process. It's good to hear that it's reliable software. You always wonder how much validation has been done with physical testing for modeling programs like this. It seems like KY Pipe is the industry standard.
Thanks again and have a great week, Steve Kowkabany, P.E.

This is the only surge program that has had significant peer review and realistically models the pressure wave effects including the additional pressure that results from the pressure wave crossing itself. It can also model pressure surge chambers to determine the effects that a curge chamber has on the system. If you are using the KY Pipe hydraulic program it is easy to import, however it is not a problem with building a model from scratch. Read the software manual because you will need to know opening times for check valves, OS&Y valves and all related valves.

We are being asked to provide this and the software KY Pipe was recommended. I'm used to just using NFPA 24 for this. It's a big underground system at an overseas manufacturing facility. Any insights or recommendations on modeling software would be greatly appreciated. Thanks and Happy New Years! Steve Kowkabany, P.E.
