Really? I've worked the FTD problem extensively and spoken with the programmers directly. It can't be used because it can't model the water supply correctly for both sprinklers operating and filling a system. This isn't my opinion but the maker of the programs direction. That was a couple years ago so I provide for something may have changed.
That said, the foam calcs aren't actually required as the means to find a design acceptable or not. They are used as a means to convey your thoughts about the criteria and have a very reasonable chance of hitting the required marks. The only way to find a system acceptable is to do a final field test. You can have paper stacked a mile high saying all is well and in actual testing if the silhouette isn't covered in 60 seconds, or last head in 30 seconds or within 5' of the wall in 4 minutes depending on the code you are using you fail end of story.

Has anyone had to do this? Is there any software to do it? I have never been asked to do this. Not to sound stupid, but would it just be a matter of taking velocity in the different pipes and adding it all up? That could easily be done in an excel spreadsheet. -- Travis Mack, SET MFP Design, LLC 2508 E Lodgepole Drive Gilbert, AZ 85298 480-505-9271 fax: 866-430-6107 email:[email protected] http://www.mfpdesign.com https://www.facebook.com/pages/MFP-Design-LLC/92218417692 Send large files to us via: https://www.hightail.com/u/MFPDesign _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org
