1st time use of this resource... I am in search of a publication for systematically troubleshooting/finding closed gate valves in a city water distribution system. I have been attempting to do this using the change in pressure from static to residual during hydrant flow tests and the fire flow 20 psi residual capacity calculation in comparison to our KY Pipe modal simulations .Thank you in advanced
We have been solving and helping others solve this sort of problem for years. Send me your email address and I can send you several papers on this. (tom.walski@bentely.com)
