I think all will agree that we've been this horse to death (and made a
little smudge on the floor where the carcass was at). so lets move on
to discussing (dissecting sometimes) other topics.

You miss my point! Why would the design velocity of a system that

never operate, but may once in a 100 years, make it last longer?
If a restriction to 20FPS makes a system last 100 yr, would a
restriction of
15 FPS make it last 150 yr?? Or maybe a restriction of 10 FPS and it
would
last 200 yrs??
So the higher the quality of the static fire sprinkler system the
slower the
water in the system is designed to move right?
Do larger than necessary pipe sizes help with reduced C factor over
time or
because of the greater interior surface area contribute more crud to
the
system than one that was properly sized?
If noise is an issue, then it should be a requirement, not a
detriment. If
water is flowing in a fire sprinkler system loud enough to make
noise, it
might be a good idea to exit the building, NOW!!!
Yes we hear of systems that last over 100 yr, but there is nothing
about
that extended life that is velocity driven.
