Not so sound snooty or arrogant (which I am neither - I was a dumb baseball player that was barely smart enough to become an engineer), I understand how fluids behave in pipes, and I have done side by side hand calcs and computer calcs for classes that I put on for AHJ's, the results were very similar. My persistence to understand engineering principles is what I have to back my last hand calc. All I am saying is I would have a lot more faith in a water delivery time program if it came from a reputable engineering firm rather than a manufacturer of sprinkler equipment.

Calc programs output you send them.FDT has the resources of the world's largest behind it, what have you got backing up the last hand calc you did? The math is too out there for any of us to follow, and since I've heard of the results for trips vs. calc for this program is very, very close, from the examples they've done, who would you rather have behind this product than TYCO? Barney and Bills Fluid get there in the right time software? http://www.sprinkcad.com/sprinkfdt.php Thom McMahon, SET Firetech, Inc. 2560 Copper Ridge Dr P.O.

I can think of a number of instances that the owner of this software has messed up before. Jim Johnston, P.E.
