i may not be following your point, but if you are concerned that the actual C-factor of old UG pipe is less than the idealized C-factor
what does it matter as long as you take your source where ever your gauge hydrant is? the waterflow test will account for any aging in the pipes, automatically. it is another thing, to extend this thinking, downstream of the guage hydrant though. There you will need professional judgement to bring value engineering. scot deal excelsior fire On Feb 13, 2008 1:19 PM, danarbel <[EMAIL PROTECTED]> wrote: > > > According to 22.4.4.7 Friction Loss, The C-Factor used for black steel > pipe > is 120. > > My question is: > > In case of using old pipe system Mains for water supply of sprinkler > system, > > > Is there in the code any requirement to find out by actual testing that > the > piping determined as adequate by the hydraulic calc procedure is indeed > adequate? > > Thanks > > > Dan Arbel > Tel: 972-4-8243337 > Fax: 972-4-8243278 > M: 972-52-2810593 > > No virus found in this outgoing message. > Checked by AVG Free Edition. > Version: 7.5.516 / Virus Database: 269.20.4/1275 - Release Date: > 12/02/2008 > 15:20 > > > _______________________________________________ > Sprinklerforum mailing list > [email protected] > http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum > > To Unsubscribe, send an email to:[EMAIL PROTECTED] > (Put the word unsubscribe in the subject field) > _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum To Unsubscribe, send an email to:[EMAIL PROTECTED] (Put the word unsubscribe in the subject field)
