It's a standard slide rule on one side and has H-W buried into the other side. I have one (that is older than me). I don't know where or if they are still available. And when the enormous check that will fund my retirement clears you can have mine. Otherwise, I'd still classify it as hand calcs, put the formula into an excel spread sheet. Can balance easily. I don't even try grids but even that would be possible. You should be able to calc any tree in less than 10 minutes with excel. I use both tools for estimating, but no reason they can't be used for submissions. I'll email anyone that wants my spread sheet. Be warned it's utilitarian not necessarily pretty. Also in there is graphing water supply curves (not log on the axis), C-factor conversions and volume of pipe formula. Chris Cahill, 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) _______________________________________________ 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)
