Never mind Roland, dumb question, of course you did.
The main reason I wanted to check it out was to see how you adjusted the
K-Factor. Then I saw in 13-2010 the formula for doing this. In my original
post I got
From NFPA 13-2007, 22.4.4.5.1, we are required to, among other things,
adjust the K-Factor.
Using the Hazen-Williams friction formula, 62.4 lb/ft3 / 144 in2 = .433
lb/in2/ft(h).
If we have an AF solution at 65.5 lb/ft3, / 144 = .455 lb/in2/ft(h).
If K=5.6, and we assume P=7 PSI.:
I'd be concerned that you have completely muddled up kfactors for someone who
no longer looks at it as the standard and industry practices do.
But why listen to us warning about sending novices out with the wrong
viewpoint?

I would strongly caution against using this method for estimate calculations.
(Without doing extensive testing to verify that it is accurate)
The D-W and H-W calculation methods are simply approximations of how fluids
interact with themselves and the pipe they are in. The H-W equation and the

lot--and with George's earlier comments.

Keep in mind that you started with a nominal K factor of 5.6. Per Table
6.2.3.1 (NFPA 13 - 2007), the range for the K factor under laboratory
testing conditions was 5.3
