Duct sizing
Hi TonyS. I like that HandBook way of looking at ducting,thanks .There is a lot of 8" high supply trunks in residential. But, on the return duct sizing we try for .08"w.c. depending or .06"w.c. depending. Our returns are larger than our supplies.

Thanks Tony.
That is a mighty handy cheat sheet. I feel your pain. Things don't come out of the old Noggin' as fast as they used to.
