The amount of significant digits we work to in various aspects is quite varied. Some folks believe calc programs down to the .001 level when it all comes down to a gauge bouncing around in a variable water supply with uncontrolled changes. Yet we worry about inches in other areas.

I am really more interested in the reasoning for the DEFINITION in NFPA #13, not some box of heads in RTI limbo. Any TC members out there not totally fed-up with me yet? _______________________________________________ Sprinklerforum mailing list Sprinklerforum@firesprinkler.org http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum _______________________________________________ Sprinklerforum mailing list Sprinklerforum@firesprinkler.org http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum _______________________________________________ Sprinklerforum mailing list Sprinklerforum@firesprinkler.org http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum
