venting capacity of 1/8"?

jpf321jpf321 Member Posts: 1,558
does anyone know the venting capacity of 1/8" pipe? thanks. i know 1/2" = about 8 gorton #1's. and 1/2" has internal area of 0.196 vs 1/8" with internal area of 0.012

is my math the correct when i say that 0.012/0.196 = 0.06 or 6% and therefore 1/8" = about 6% of 8vents = 0.48 gorton #1's? that doesn't make any sense .. since a Gorton 1 = a gorton D and we have gorton Ds on 1/8" all the time,
