Thank you,Don.
And, thank you, BOSS. And your family, (for allowing you to spend the time and resources).

Don,

As the song goes, "Have a happy Texas Christmas, y'all!"

Daily, I give thanks for your efforts. I spread the HVAC-Talk gospel to those knucklheaded students of mine. Some day they will see the light.

It's been a good year and much of it is due to this site
(gosh, I need a life!?!)

Blessings to you and yours,

Don,
I'm new to the posting thing here on the site. But i've been a reader on the site for along time. I love the site and would like to say thank you for all the work you and everyone does to keep it clean and informative.

I recently posted a very general question about static pressure in ducts and the sizing that goes along with that topic. I guess I got the answer that I thought I would get.
The manual J and the manual D, was basically the answer I got.

I guess I was trying find out a short cut.

More or less. After we take and load the house with the manual J and have the size of the unit needed and the total cfm. Can we just take the acca ductulator and assume a .08 static for the supply, .05 static for the return and size for rigid duct and come out somewhat to the good?

Or "must" we layout the duct by adding up the total equivalent feet and determine the actual pressure drop for the duct, and then go to the manufacturer specs. for the fan performance and etc....???

Is there a short cut? or would we be cutting the customer short of what they are paying for and not get the performance out of the system that we promised them?

Just looking for some feed back on this matter. Thanks and again Merry Christmas!!!!!
