Airway Size In Artisan Pipes

[lestrout]

HowlingW - you make a good point that there is a big difference between 3 and 4mm. But the difference is even greater than the 33.3333% increase in diameter. This is because the air flow relates to the cross sectional area of the airway, and the calculation involves squaring the radius. So 1.33 squared is almost 78% more in area.

Ah okay Lester, if you say so. What has to square with me, is that the pipe smokes well for me. There is no set numerical computation that concerns me. Either it does or it does not.

Some pipes I pack tighter than others

I'll buy that! I just finished cleaning up an old Chacom 8" long Canadian; one of those that has 2 pieces spliced for the shank. The bore is 3mm and my drill bits are only 6" long, so I decided to open the stem to 3mm and leave the shank alone. Glad I did!! Easy puffs, plenty of flavor; a great smoker:-)

If it ain't broke, don't fix it.

I have a habit of getting wild with a drill. I really like an open shank. I tend to leave the stem alone after a couple of mishaps. My preference in pipes is a tapered bowl and a loose draw.
