Bullk Reation Coefficient
Is there an industry standard for a bulk reaction coefficient when beginning a design. I am connecting a pipe to an existing distribution system. I know the initial Cl- content. I am trying to juggle fire flow and quality. I am using EPAnet to water the system. Is there an acceptable value to use for the reaction coefficient or is the only option to perform a jar test on a sample of the water? I find it hard to believe that there are no good resources on this in the vast spaces of the internet.
EPAnet says to use -1 but I assume this is a general value. I also assume that since fire flow usually dictates pipe size that modeling quality is not really a top priority and is simply dealt with after the fact. This may be why there is not a lot of info out there regarding this coefficient.
Thanks in advance.
