Yes I have. Your education is not my problem. Necessity is the Mother of
invention and a number of other things. I strongly suggest that you do
your own research. Anyone here that owns a Decent ductwork manual and/or
software has those figures. You want those.. get off your ass and look
them up. Try Barnes and Nobles in the Engineering section.

REPLY: If you have actually measured static pressure in a Mobile Home
thats a double-wide, then why cant you be helpful by offering up this
info ? It has nothing to do 'with my education' ; I simply dont work
on Mobile Homes but would like to know. If it is too much of an
imposition asking you as a fellow HVAC person, then please dont
respond to my post if you have to portray yourself with a big ego and
bad attitude which is all too common in this Trade . If you have the
opportunity to help someone in the Trade, you should ... instead of
causing dissension . What is behind your attitude anyways ?? If its
that you are overworked , bit off too much of a house mortgage, and/or
have 6 mouths to feed, etc... then please dont take it out on me cause
i didnt buy your house or get your wife pregnant. This Trade doesnt
need any more cocky people with superiority complexes -- thats whats
making the Trade look bad overall and especially to consumers.
Please change . Regards.

So you said that you don't do mobile homes.... no problem, then you don't
need to worry about it anyway. If you *DO* work on trailers, then take the
measurements yourself every time you work on one. Just remember that the
"normal" ductwork in a trailer will only handle 300cfm per ton, instead of
the normal 400cfm.

REPLY: Im 'not worrying about it' ; Im simply curious . Youre not
another arrogant tradesman with a problem like Don, are you ???
Thank you for sharing the nominal 300 cfm per ton criteria . Its a
shame you had to include a bunch of guff with it though. Its really a
shame a NG like this cant be more civil and a source of help , instead
of one thats filled with animosity, pride, arrogance, and the
typical "F this / F that" attitude of most . Id like to see such a
NG close down .

A true American... shut down the Second amendment because you walk in
uninvited and don't like what you hear. I wonder if we walked into your
home and arrogantly demanded that you do our work for for us.. Would you
be accommodating or just the crude cretin that you appear to be.
