Brian, I have always found the appendix of the reference book "Hydraulic Calculations of Automatic Sprinkler Systems" by Pat Brock to be a fantastic and easy to use reference. It has a full set of charts showing Hazen friction loss values by pipe material, schedule, size, C-factor, etc. I'm sure there are other reference books with these charts as well.
As Karen said, spreadsheets are great for this as well if you are not using sprinkler design software. However, I would be cautious when using plumbing codes or other hydraulic reference charts to make sure they are based on the Hazen Williams equation and not the Darcy-Weisbach friction loss equation, which is more common in other industries. Good luck, Steve Kowkabany, P.E.

I know the formula that's in the book but I was hoping there might be a reference chart or something you could use instead. I have a "Construction Master 5" calculator for working with feet and inches but it's not set up to do compound formulas like the Hazen-Williams, sure would hate to have to buy another one just to do formulas....... _______________________________________________ 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)
