My pleasure Duane, thanks for saying. I use FDS-SMV (Fire Dynamics Simulator-Smokeview. FDS does the calculations and out-puts numbers. Smokeview is a 3D graphical representation of the results of the calculations (my favorite part). The software has been under development for 20+ years, and available to the public for about 12 years. I have been using it for 6 years, and the more I learn, the less arbitrary NFPA #13 becomes :). I should mention, instead of starting the fire and letting it grow at some rate, the heat release rate went from 0 to 2 MW in 1 sec, similar to the 'oven plunge test' method of measuring RTI. I am now curious to see the activation times under more natural conditions. If you or any Forumites are interested in getting into FDS, I would be happy to help you over any initial humps you might be having trouble getting over, off Forum of course, and over lunch time in Kansas. _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum
